Which kind of marketing channel is better for hardware products

Hardware products can be divided into hardware accessories and daily necessities from the use. Different products have their own marketing channels. In recent years, with the entry and maturity of e-commerce channels, some hardware manufacturers are at a loss for the overall marketing channels. So, how many channels are there, such as professional markets, big stores, self-run stores, franchise stores, e-commerce direct sales, and what kind of effect is better to enter?

Professional Market: Suitable for Middle-end Brand Cluster Management

Professional market has several notable characteristics: first, the industry attribute of the market is strong; second, there are many clustered businesses and brands, each with different areas of independent shops; third, the management category is perfect, can satisfy the one-stop purchasing of buyers; fourth, the market is convenient, customers can drive freely in and out, and carry goods in batches. For example, the hardware market in Shenzhen South China City, the hardware Electromechanical market in Xi’an and Zhengzhou South China City, etc., provide a huge space for purchasers to compare and choose from different aspects of brand, category, price and merchants. Therefore, since the date of operation, it has attracted both supply and demand sides to enter the market. Generally, high-end brands have their own fixed customer groups and channels. It is difficult for middle and low-end brands to compete with them. On the contrary, the emerging professional market is completely open, providing a fair marketing platform for all mature brands and growing brands.

Therefore, the cohesion of large-scale professional market for both supply and demand sides is obvious, its characteristic is the word “professional”, which attracts professional businessmen; on the contrary, some small markets will inevitably be phased out because of traffic problems, old city renovation problems, fewer suppliers and other issues. As the majority of small and medium-sized hardware production enterprises, whether operating accessories or finished products, they should first enter the professional market to build channels, in order to make marketing radiation further.

Big Market: Suitable for High-end Consumer Brands to Enter

The so-called supermarket simply means that tens of thousands of goods are sold together. Because of its high-end, big stores are different from daily grocery stores, convenience stores, wholesale markets and other channels. In the form of retail sales, it attracts the neighboring residents to purchase and consume.

Industry insiders believe that: consumer hardware chooses to set up special counters in brand stores. On the one hand, it wants to build its brand influence with the strong appeal of the stores; on the other hand, it also takes into account the environment, marketing and service system of the stores, which are easy for businesses to operate.

But as the rent of the stores is getting higher and higher, the stores keep opening, and the cost of raw materials and logistics is also increasing. The rising tide brings high cost to the channel of hardware industry. And the same products, and many large brands to compete, their final sales, whether they can meet the expectations of entry? Moreover, once established a relationship with the store, the enterprise will inevitably have dependence, business will be very passive, which requires hardware manufacturers to seriously consider and balance.

Self-operated Shop: Products with Unique Characteristics and Advantages are Suitable for Self-operated

In order to establish a controllable marketing channel, in recent years, more and more hardware enterprises have focused on the opening and management of their own stores. The advantages of self-owned stores are obvious. On the one hand, they can establish brand image, organize free promotional activities and increase marketing efforts; on the other hand, they can restrain bad behavior of stores through a unified price system. Through the quality assurance of the unified system, the unified standard of after-sales service, and the common attention and supervision of the public, ultimately promote the improvement of customer service level and increase sales.

However, the cost of investment in economy and manpower is very high, which has become an important factor to test the development of enterprises. With the rise of social prices, store rent, employee treatment and training costs are rising. In the fierce competition environment, the opportunities and costs brought by self-owned stores are like a double-edged sword. The pros and cons of self-owned stores depend ultimately on the business operation and market segmentation.

But one thing is certain, that is, the more unique advantages of products, the more suitable for opening self-owned shops.

Machining of Cylinder Barrel of Hydraulic Cylinder

Cylinder barrel is the main component of hydraulic cylinder, mine monomer prop, hydraulic support, gun barrel and other products. Its processing quality directly affects the life and reliability of the whole product. Cylinder barrel processing requirements are high, its internal surface roughness requirements are Ra0.4-0.8 & um, and strict requirements for coaxiality and wear resistance. The basic feature of cylinder barrel is deep hole processing, which has been puzzling the processors.

Because of the residual compressive stress in the surface layer, the rolling process is helpful to the closure of micro cracks on the surface and hinders the propagation of erosion. Thus, the corrosion resistance of the surface can be improved, and the generation or expansion of fatigue cracks can be delayed, so the fatigue strength of cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thus improving the wear resistance of the inner wall of the cylinder and avoiding the burns caused by grinding. After rolling, the surface roughness decreases, which can improve the matching properties.

Cylinder is the most important component of construction machinery. The traditional processing method is: broaching cylinder block – precision boring cylinder block – grinding cylinder block. The rolling method is: broaching cylinder block – precision boring cylinder block – rolling cylinder block, the process is three parts, but the time comparison: grinding cylinder block 1 m in 1-2 days, rolling cylinder block 1 m in 10-30 minutes. Contrast input: grinding machine or quilting machine (tens of thousands – millions), rolling knife (tens of thousands – tens of thousands). After rolling, the surface roughness of the hole decreases from Ra3.2-6.3um before rolling to Ra0.4-0.8-um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the cylinder increases by 25%. If only considering the influence of cylinder, the service life of cylinder can be increased by 2-3 times, and the efficiency of boring and rolling process can be increased by about 3 times than that of grinding process. The above data show that the rolling process is efficient and can greatly improve the surface quality of cylinder.

After rolling, there is no sharp edge on the surface of the cylinder, and the sealing ring or seals will not be damaged by long time moving friction, which is particularly important in the hydraulic industry.

What should we pay attention to when purchasing the spring used in the vibrating screen

What should we pay attention to when choosing the spring of vibrating screen? The following four points will be used to make a simple analysis for you:

1. The suitable rubber material should be selected according to the sieving material, environment and conditions, as well as the specific gravity and static electricity of the material itself.

2. Attention must be paid to the bonding degree between rubber and metal to avoid stress concentration at the bonding surface.

3. Technically, in order to improve the service life of shear deformation isolators, Alide machines usually give proper pre-compression in the vertical shear direction, which hardens the stiffness in the compression direction and softens the stiffness in the shear direction.

4. If there is resistance, energy must be consumed. This part of lost energy is converted into heat energy. Rubber is a bad conductor of heat. In order to prevent excessive temperature rise from affecting the performance of rubber isolators, rubber isolators should not be too large. Structurally, measures should be taken that are easy to dissipate heat, or natural rubber materials with less heat generation should be selected. Because rubber isolator can convert part of energy into heat energy, reduce vibration energy and achieve the purpose of vibration reduction, so rubber isolator is often called shock absorber.

1. Hook

There are many kinds of hooks, there are very standard plastic hooks, there are some strange shapes. Generally speaking, no matter what kind of accessories, the stranger the shape, the less use it will have. Who calls a person too professional? Here are some typical introductions. Plastic hooks are seldom used in external systems, because during the travel process, things outside the package are easy to collide, and plastic things, no matter how hard they are, are also vulnerable to damage. Generally large hooks are often used on the backstrap of a waistbag or leisure schoolbag, and are used with D-rings on both sides of the bag. Small hooks are often used in bags to hang keys and other things. The hook on the left is strong enough to rotate and has metal spring openings, thus avoiding the disadvantage of easy breaking with plastic openings. Usually used for single shoulder bag strap and D ring connection. This strength of the hook is sometimes used on the outside of the load. The small hook is usually used to hang small bags, keys and other small items in the bag.

2.D-ring (DRing)

D-ring, named for its shape like the letter “D”. It has a wide range of uses. It is often used to fix pipes on the back strap or hang small objects (do many donkey friends often put towels in D-rings to wipe sweat on their faces when they are on the road?). There are not many kinds of D-rings. The arc is smooth and suitable for use with forefinger or thumb, so some bags will design the D-ring in place to support the force. For example, a larger travel bag has a D-ring in front of its right strap, which is designed to use the right hand to assist with the afterburner when the bag is too heavy. Sometimes the plug-in system uses a D-ring.

3. Square Loop

Like D-rings, square rings are named for their shape. Square rings are often used in plug-in systems. For example, a general mountaineering bag has four square rings on its cover, which can be used to hang things like sleeping bags. The square ring can be used in conjunction with an elliptical three-stop buckle and can be fastened like a button on a garment. It is easy to attach a small hanging bag to the backpack. It can also be used as a square buckle.

Detection of Hardware Stamping Parts

Rockwell hardness tester is used for hardness testing of metal stamping parts. Small stamping parts with complex shapes can be used to test the plane is very small and can not be tested on ordinary desktop Rockwell hardness tester.


Stamping process includes blanking, bending, drawing, forming, finishing and other processes. Stamping materials are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.


PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are the most commonly used parts in the field of metal processing and mechanical manufacturing. Stamping parts processing is a method of separating or forming metal strips by means of dies. It has a wide range of applications.


The main purpose of hardness testing of stamping materials is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping process. Different kinds of stamping process require different hardness levels of sheet metal. Aluminum alloy sheet used for stamping can be tested by Wechsler hardness tester. When the thickness of material is more than 13mm, it can be changed to Barkholder hardness tester. Pure aluminium or low hardness aluminium alloy sheet should be used Barkholder hardness tester.


In the stamping industry, stamping is sometimes called sheet metal forming, but it is slightly different. The so-called sheet metal forming refers to the forming method of using sheet metal, thin-walled tube, thin section as raw materials for plastic processing, which is collectively called sheet metal forming. At this time, the deformation in the direction of thick plate is generally not taken into account.

2. Corrosion resistance: Aluminum alloy base and sliding base can be selected. Its surface can be passivated by high corrosion resistance and wear resistance aluminum alloy (natural anodic oxidation treatment). In addition, stainless steel linear guide rail and installation screw are all made of nickel plated material with special treatment, so it has sufficient corrosion resistance.

3. Structure and specialty: Pneumatic sliding table is a single-axis intelligent combination unit which can be installed with LM linear guide rail and aluminum alloy base and combined with cylinder drive. Transportation is its main use.

4. Component standardization: realizing modular component standardization of pneumatic equipment. Horizontal and vertical directions can be used in handling, transmission and conveying operations. The pneumatic sliding table module can replace the cylinder and has the advantages of low price, long service life and easy maintenance.

Technological Characteristics and Quality Factors of Metal Cutting

Technological Characteristics and Quality Factors of Metal Cutting

With the continuous development of machine tools and cutting tools, the accuracy, efficiency and automation of cutting process are constantly improving, and the application scope is also expanding, which greatly promotes the development of modern machinery manufacturing industry. There are many classifications for metal cutting. There are three common classifications: according to process characteristics, according to material removal rate and processing accuracy, and according to surface forming method. The main factors affecting the quality of cutting are machine tools, tools, fixtures, workpiece blanks, cutting oil, process methods and processing environment. Following is a brief introduction of the common types of metal cutting technology and methods to improve quality.

I. Characteristics of Cutting Technology

(1) Large-scale

With the increasing size of parts and the high efficiency of parts, a multi cavity mold is required, which makes the mold more and more large-scale, requiring large operation, large shaft stroke, heavy bearing, high rigidity and high consistency.

(2) Complexity

With the complexity of the shape of die parts, it is necessary to improve the design and manufacturing level of the die. The multi-functional composite die with various grooves and materials forming or assembling components in a set of dies requires a large amount of process programming, high comprehensive cutting ability and high stability of deep hole cavity, and improves the processing difficulty.

(3) Precision

The refinement of die processing makes the compounding and high efficiency of processing equipment more stringent. High-speed milling has many advantages, such as Machinable high-hard materials, stable processing, small cutting force, small workpiece warming deformation and so on. Die and mould enterprises pay more and more attention to high-speed milling

Types of Cutting Technology

(1) Classification by process characteristics

The technological characteristics of cutting depend on the structure of cutting tool and the relative motion form of cutting tool and workpiece. Generally, it can be divided into turning, milling, drilling, boring, reaming, planer, slotting, broaching, sawing, grinding, grinding, honing, ultra-precision processing, polishing, gear processing, worm wheel processing, thread processing, ultra-precision processing, fitter and scraping.

(2) Classification by process accuracy

According to material removal rate and machining accuracy, cutting can be divided into rough processing, semi-finish processing, finish processing, finishing processing, decoration processing, ultra-precision processing, etc.

(3) Classification by surface forming

In cutting, the machined surface of the workpiece is obtained by the relative movement of the cutting tool and the workpiece. According to the surface forming method, cutting can be divided into three categories: tool path method, forming tool method and generating method.

3. Ways to Improve Quality

Cutting quality mainly refers to the machining accuracy and surface quality of the workpiece. The main factors affecting the cutting quality are machine tools, tools, fixtures, workpiece blanks, process methods and processing environment. In order to improve the cutting quality, appropriate measures must be taken in the above aspects, such as reducing the working error of machine tools, selecting cutting tools correctly, improving the quality of blanks, arranging the process rationally and improving the environmental conditions.

(1) Selection of process methods

Each kind of surface has a variety of processing methods, and the specific selection should be based on the Parts’processing accuracy, surface roughness, material, structural shape, size and production type, select the appropriate processing methods and processing programs.

(2) Determination of process steps

The general principle of working procedure arrangement is to process the datum first, then other surfaces, first roughing and then finishing, roughing and finishing independently. Two important factors should also be considered in the specific operation to minimize the clamping times so as to improve efficiency and ensure accuracy.

(3) Measures to ensure accuracy

The process assurance measures of key dimensions and technical requirements are very important for the design of process plans, so as to avoid the factors such as clamping deformation, thermal deformation, and processing ripple caused by workpiece vibration affecting the processing quality of parts.

(4) Use of cutting oil
Cutting oil is a kind of medium which must be used in metal cutting process. It mainly plays the roles of lubrication, cooling and cleaning in the process of processing. Special cutting oil contains vulcanized extreme pressure and anti-wear additives, which can effectively protect cutting tools and greatly improve process accuracy.

Why do bimetal band saw blades lose teeth

Why do bimetal band saw blades lose teeth?

Many people don’t know the use of bimetal band saw blades. How did they lose their teeth? Or is it called teeth beating or broken teeth? Next, we summarize the following reasons for users by synthesizing years of experience:

1. The sawing machine is shaken by the surrounding forging equipment.

2. The sawing machine is unstable and trembling.

3. Workpiece is not tightened and loosened during sawing.

4. Anti-alignment of saw band teeth.

5. Inappropriate selection of tooth shape, too large or too small pitch.

6. Saw frame descends too fast and improper operation causes tooth tip to impact workpiece.

7. The new belt does not run in.

8. The clamped workpiece has slag inclusion and hard point.

9. The top guide block is damaged. When sawing, the saw band rises and the serrated teeth collide with the side guide block.

10. When the lifting cylinder enters the air, the oil quality is not good, the cylinder is worn out, and the control valve is out of control, all of these make the sawing frame unable to descend uniformly, resulting in teeth beating.

Please pay attention to the above ten points, which will greatly reduce the probability of bimetal band saw blade teeth.
