What are the characteristics of the oil glue compound machine equipment

The oil glue compound machine is a combination of two or two layers of materials and adhesive, so that raw materials can get new functions. Such as film, aluminum foil, film, paper, non-woven fabrics and so on. It can also be combined with films, sponges and fabrics, while ordinary soft packaging materials are basically composite products.

It is generally believed that the oil glue compound machine is a kind of compound equipment, such as home textile, clothing, furniture, automobile interior decoration and so on. It is mainly used in all kinds of fabric, leather, film, paper, sponge layer or multi-layer composite. The concrete is divided into rubber composite material and rubber composite. The rubber composite material is divided into water rubber oil, PU glue, hot melt adhesive and so on. The composite process of non adhesive direct hot press or the use of flame composite material.
The characteristics of the equipment are as follows: 1. These two layers of materials can be bonded together to make the composites fastness better. At the same time, it can also be used for the adhesion of three layers of thin materials, so as to increase production efficiency and reduce production cost. 2. The double rubber groove mesh belt is combined with high temperature net and pressed to make the composite fully exposed to the drying cylinder to improve the drying effect and make the processed material soft, washable and fastness. 3. This machine is equipped with automatic infrared adjustment device, which can effectively prevent the deviation of the net belt operation and prolong the service life of the net belt.

What is the working principle of a bronzing machine

The bronzing machine produced by the bronzing machine manufacturer refers to the process of stamping the electrified aluminum foil to the surface of the substrate under certain temperature and pressure. The graphic and text of the mechatronic mechatronic aluminum stamping shows a strong metallic luster, brilliant color and never fade, especially gold and silver electrified aluminum, which embellished the surface of the printed matter with its magnificent, exquisite and elegant decoration, enhanced the artistic character of the print, and played a protruding effect on the theme; its brightness is much more than the print. Gold and silver seal make the products feel superior and enjoy the beauty.
At the same time, due to the excellent physical and chemical properties of the electrified aluminum, it has played a role in protecting the printing products, so the gold stamping process is widely used in the high-end, exquisite packaging and decoration trademarks, calendars and books and magazines. Secondly, the electrochemical aluminum stamping range is very wide, from the general book cover, trademark pattern, publicity. Advertising, plastic products to daily department stores, from paper to leather, cotton cloth, etc.; then, hot stamping is a dry processing method, workpiece after hot stamping can be immediately packaged and transported, so, hot stamping technology is widely used, the scope of application of stamping is still expanding.
The working principle of the gold stamping machine produced by the manufacturer of the gold stamping machine is mainly: using the principle of hot pressing transfer, the electrochemical aluminum is electrified with the printing plate and the printed material under the pressure of pressure. The heat of the electrothermal plate makes the printing plate have certain heat, the electrochemical aluminum is heated to melt the dyed resin layer and adhesive of the hot melt, and the adhesive force of the resin layer is dyed. The viscosity of the special thermosensitive adhesive is increased and the aluminum layer and the electrochemical aluminum film peel off to the substrate. With the removal of the pressure, the adhesive is quickly cooled and solidified, and the aluminum layer firmly adheres to the substrate to complete a stamping process. From the formation of the electrified aluminum and the mechanism of the stamping, the ideal will be desired to obtain the ideal. The electrochemical aluminum foil used for stamping must conform to the following requirements: uniform color on the bottom layer, no obvious chromatic aberration, coloring and color spots, smooth, white and no impurities, no obvious stripes, sand points and oxidation phenomena, good gloss, strong firmness, high clarity and correct model.

The price of production of powder metallurgy technology

Hardware tool accessories production price how to using powder metallurgy technology?
Powder metallurgy is a process in which powder metallurgy die is assembled on powder metallurgy automatic molding press. After debugging, it is pressed into blank and then sintered into metal solid blank, followed by a small amount of processing and heat treatment process according to the requirements of the product. Powder metallurgy is suitable for mass production, the general requirements of more than 10000 production batches.
Powder metallurgy products generally offer: 10 grams more than ordinary steel products, one in 2-3 grams
More than 10 grams of copper carbon alloy steel products, one gram of 3-3.5
Copper nickel alloy steel products more than 10 grams, one gram of 3.5-4
Copper bearing more than 10 grams of the product, 0.11-0.14 yuan a gram
Stainless steel products more than 10 grams of the product, 0.11-0.13 yuan a gram
According to the actual requirements, powder metallurgy technology product structure, size, tolerances, payment methods, appropriate changes.
The price of P / M products is much more affordable than that of machined products, and there are many processing procedures and high labor cost, especially for some heterosexual products and structural parts. So in the company or individual in the choice of manufacturers, some machining products can give priority to find powder metallurgy quotation.
As for the powder metallurgy casting products and price advantages and disadvantages, this is about the same. But the production capacity of powder metallurgy production precision and stability was far better than casting.

The difference between the color powder of the plastic mould and the color parent

Today, a client came to discuss with me the product for a new color. And it requires that it can’t fade. I listened and shook my head with a smile, explaining it to him in detail.

There is no absolute fading product in the world, and the products that use color pink mother color are still likely to fade, but the degree of color fading in different colors is different, some are more obvious, some are difficult to detect.

Plastic coloring products will be faded by a variety of factors. The fading of plastic coloring products is related to pigment, dyestuff’s light fastness, oxygen resistance, heat resistance, acid resistance and alkalinity and the properties of the resin used. The above properties of pigments, dyestuffs, surfactants, dispersants, carrier resins and anti-aging auxiliaries must be comprehensively evaluated before production.

The color masterbatch is pretreated first, it has high coloring force, the quantity can be reduced and the quality is stable. The transportation, storage, use and environmental pollution are greatly reduced. In mass production, we usually use color masterbatch.

Color powder is a dispersant that eliminates the surface air by wetting and permeating the pigment, disperses the aggregates and aggregates into fine, stable and uniform particles, and no longer condenses during processing. The commonly used dispersants are low molecular weight polyethylene wax, and EVA wax or oxidized polyethylene is used for the more difficult dispersed organic pigments and carbon black. Wax, the synthesis of low molecular weight polyethylene wax and polyethylene pyrolysis method of low molecular weight polyethylene wax is very different.
Plastic color powder

Other additives, such as coupling agent, antioxidant, light stabilizer, antistatic agent, filler and so on, are added as requirements and varieties, called multi-functional masterbatch, and add brighteners, which are beneficial to mould molding and surface luminance. The color powder is used for the convenience of manufacture. Under normal circumstances, we usually use toner for small quantities of products. Because the color powder is simple to manufacture. The advantage of fast speed.

What are the skills of sheet metal bending and machine maintenance

With the development of economy, sheet metal processing products are almost everywhere in our daily life, so we can see how important the sheet metal processing is in our life. Today, Xiaobian is going to talk about some skills of sheet metal bending technology and machine tool maintenance.
1, in the work to work diligently, think more, in each processing of a product, with notes, different products, what kind of mold, order, etc., so that in the future work at any time check.
2, when installing the mold, try to install the mold in the middle part of the machine tool, so that it can not only ensure the accuracy of bending, but also extend the service life of the machine tool.
3, in the case of some dimensions with slight deviation, the adjustment method of sheet metal bending processing: fixed expansion size, with different mold, bending size will be different, the lower die V, the larger the bending size, the smaller the V of the present die, the smaller the bending size will be smaller.
4, in the arrangement of bending order, if you can do no bending surface positioning, try not to position the curved surface as far as possible, so that the accuracy of the bending size can be ensured.
5, when bending some small size products, when normal methods can not be achieved, they can be pressed or bent or eccentrically.
The above points are some techniques for sheet metal bending and machine tool maintenance. In addition to the above methods, there are many methods of sheet metal bending processing, which require us to learn in a long period of practice to master.

The best state of man: not to read the past, to fear the future

Every time I pass a kindergarten, I hear friends complaining: “I envy those kids. They are carefree every day. Not like us, they are full of troubles.”
Who was looking forward to growing up every day, stealing his mother’s lipstick, and dancing with his high-heeled shoes awkwardly in front of the mirror? Now, who excludes growing up, repels maturity, and wants to go back to childhood?
People are really a contradictory combination, but years will not let everything go back to you because of your contradictions.
I saw my friend so pessimistic and pessimistic. She patted her on the shoulder and comforted: “you can not interfere with yourself, try to put aside your worries.”
All the little things in your life that you have always been obsessed with. You are always thinking about it, but because you are afraid of facing the future.
When you were 20 years old, you would miss your childhood, your company with your cicadas, and dance with butterflies.
When you are 30 years old, you will miss your 20 year old self.
When you are 40 years old, you will miss your 30 year old self. It will be a sweet burden on your shoulders.
People always worry about the past, and the unknown always makes people feel embarrassed. As a result, you let memories dominate life, and can’t go back to the past, nor can you step into the future.

The generality of hardware accessories

Hardware fittings have higher requirements for versatility, interchangeability, functionality and decoration. The diversification of the base material, the reform of the structure and the increase of the function of use, the function of the furniture hardware is no longer only the connection of the decoration and part of the movable parts. The function of the furniture is more and more strong, and the areas involved are becoming more and more wide. It will improve the production efficiency, lower the cost, improve the quality of the product and enhance the quality of the product. The competitiveness of the domestic and foreign markets and the creation of benefits have played a positive role. The development and introduction of the hardware accessories of the Xiong tiger mountain, the renewal and improvement of its function, style and quality also endow the constant update and development of the style and function of the home. Furniture home hardware can be roughly divided into two categories: decorative hardware and functional hardware. Today, with the development of industrial production level, under the guidance of industrial design theory, the two are gradually moving towards the brand.

Common problems and daily maintenance of punch dies

First, the main reason for the fast wear of the punch is:
(1) the mold clearance is small. It is generally recommended that the total clearance of the mold is 1/4 of the material thickness.
2. Convex and concave mold is not good for neutral, including mold base and die guide components and the inaccuracy of the turret inserts.
The punch temperature is too high, mainly due to the continuous stamping of the same mould for a long time.
4. Improper mold grinding method causes the die annealing and wear aggravating.
(5) partial unilateral punching and cutting, the side force will cause the punch to be biased toward one side and cause the die to wear seriously. If the precision of the machine tool die is not high, the punch will go over the die and cause the punch and die to be damaged.
The performance of the stamping oil is not up to the processing standard, and the oil pressure is released instantaneously during the pressing process, resulting in wear and tear in a short time.

Two. The problem of die tape
(1) the sharpness of the die edge, the larger the edge of the blade, the easier it will be to rebound.
2. The modulus of the mold and the small modulus of the machine tool position will easily cause the waste to rebound.
(3) if the clearance of the mold is reasonable, if the mold gap is not suitable, the waste will rebound easily.
(4) is there more oil on the surface of the processed sheet?
Fatigue damage of spring.

Three. The neutral problem of the mold
(1) the design or machining accuracy of the machine tool is not enough. It is mainly that the upper and lower turntable die mounting blocks are not good enough for neutrality.
2. The accuracy of mold design or machining can not meet the requirements.
(3) the precision of the guide sleeve of the die bump is not enough.
The selection of die clearance is not suitable.
The wear of mould mounting base or mould bushing due to long-term wear is not good for neutrality.

Four. The correct use and maintenance of the mold
Before mould installation and use, the guide sleeve and mould of the mould should be strictly checked for lubrication.
Regularly check the rotary table of the punch and the installation base of the die to ensure the coaxial accuracy of the upper and lower turntable.
(3) install the convex and concave die on the turntable according to the installation procedure of the die, ensure that the direction of the concave and concave die is consistent, and prevent wrong loading and reverse loading.
After mold installation, check whether the fastening screws of the mould mounting base are locked correctly.
When the punch and die edge of the punch die are worn out, the wear degree of the die blade, the wear of the die, the quality of the stamping parts and the life of the die will be reduced.
6. The general dies used for mass production should be backed up so as to rotate production and ensure production.
Stamping tools should be operated with soft metal to prevent damage to the mold during knocking and smashing.
The mold should be handled gently in the course of transportation so as not to damage the edge and guide of the mold.
The mold should be put back to the designated position in time and used for oil and rust prevention.
We should regularly replace the springs of the moulds to prevent the fatigue damage of the springs from affecting the use of the moulds.
Tech_7

In addition to the reasonable die structure, high manufacturing precision, good heat treatment effect and the correct selection of stamping oil and the precision of the die installation, the correct use, maintenance and maintenance of the die can not be ignored. By using the self developed vulcanized lard and sulphide fatty acid ester as the main additive, it has a good performance of extreme pressure and abrasion resistance. It can effectively improve the surface finish and processing efficiency of the workpiece, and have no harm to the human body, the workpiece, the equipment and the environment. It is the reference of many metal processing enterprises in China. The partners have been well received by customers at home and abroad in practical applications.

Maybe a list can change the fate of a company

Perhaps a list can change the fate of a company, and do not despise anyone or anything.
I am made of powder metallurgy products.
On December 10, 2017, Sunday morning, 10, I received a phone call from the north. Are you a manufacturer of powder metallurgy products? I have two products with a lot of demand here. A king of our company is looking at the market in Zhejiang. It is required to choose a regular manufacturer with strong strength, technical strength and management. Can you come to your company in the afternoon to see it?
Yes, of course, I said. But in my mind, we have a rest in the factory today. If the customers come, I can’t see the hot work scene, and I myself and my wife and children just play outside. If I come in the afternoon, I have to finish the journey.
But the customer is God, can not let go of every opportunity to share business and products with customers, the customer’s request is military intelligence, must meet their needs. Next, I said to my client, “good afternoon, I will wait for Wang Zong in the company.”
We also ended our little journey early and went back to the factory to wait for Wang Zong to come.
But when more than 5 of the customers did not come, the letter to Wang asked the general situation, Wang said that because of the time in Wenzhou can not be arranged, tomorrow morning to my company.
At 9:30 in the morning of No. 11, Wang did come to our company to investigate and negotiate. We talked very happily. Wang’s general professional and personality charms are quite strong, but there are many problems to be solved. From the customer’s needs, we have accumulated many years of technical experience and contacts. It is ignorant.
In the end, we won this small list, if done well enough to change the fate of our company.
Thank you, Mr. Wang, thank you for your generation. Thanksgiving life, we will work harder!
High quality, high service, almost the same price, at the same time, be good at grasping every opportunity and moving, honesty, enthusiasm, Thanksgiving hospitality, fate will tilt to us.
