In the current family decoration, we have a lot of consumers to choose to install push and pull type doors or windows, then it is necessary to design the pulley. It is very important to choose a good quality pulley.
A pulley is a small wheel with a groove around its axis. What we are familiar with is the pulley of the sliding doors and windows at home, and the pulley can rotate around the central axis. Pulley is the simplest lever type machinery. Good skating can not only reduce noise, but also extend the service life of doors and windows. Material of door and window pulley: Wood pulley, steel pulley and engineering plastic pulley can be used in accordance with practical requirements.
Door and window pulley buying and buying skills:
1, we must first look at the door and window pulley. The exterior design structure and color of the mixed pulley can not achieve a harmonious and unified beauty with the window and window that will be used. Only when the image is up to the standard can it be listed on the selected list.

2, next is the selection of material, you can be based on the overall decoration of the actual situation of your own aesthetic and preferences, to select the pulley from the material, but it is necessary to pay attention to the consideration of gravity. If the doors and windows are heavy and choose the metal pulley as much as possible, then if the windows and doors are lighter, your choice will not be limited, and you can pick it out.
3, as pulley is an indispensable part in sliding doors and windows, it is very important to buy a good pulley. A good pulley not only has long service life, but also can increase the service life of doors and windows, and does not produce sound during the process of pushing. You can keep a quiet environment.
Summary: push and pull the door window because of its simple and easy to operate, beautiful appearance, good sound insulation advantages, popular consumers love, most consumers in the choice, will be preferred.

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.
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.
How to get to know the automatic lathe accessories
I believe that a lot of people will feel that as a sale is very difficult, it is not easy to sell, often meet various difficulties. As a sale, not only have a mouth that will be said, but also have a very good understanding of the product. As a small editor in automatic lathe sales, automatic lathe cutting tool is the same. With accessories, a lot of kinds, each product has different features, but the most troublesome or automatic lathe parts this section, today to tell you how to better understand the automatic lathe accessories!
There are hundreds of automatic lathe accessories, the big to everyone knows, a small screw needs to communicate for a long time, not do not know the product, but to confirm whether the automatic lathe accessories needed by the purchase is consistent with the automatic lathe accessories provided by the small editor. If the auto lathe accessories are memorized by rote, it is really tired. And the effect is not necessarily big, because the automatic lathe accessories every part of the possible size is different, or the use of the model is different, automatic lathe model, sub brand model, natural accessories are to follow the classification, so want to memorize automatic lathe accessories, the best method or remember each one. Where is the accessories used!
In fact, it is very simple, but it will be difficult to do, but understanding the memory of the memory is the best way to understand each automatic lathe accessories it is used in what brand of automatic lathe, and what type of machine, and then rely on the time accumulated to remember, sometimes you remember to memorize something, but you remember it is missing. Not often meet, slowly also forget, so one side of the memory, is the best way to find the best, but if there is time to look at the automatic lathe accessories, even remember look, because as a sale, if the product is not well understood, even if you will communicate again, believe your client. You will also care about your cognitive ability.
Automatic lathe accessories, there is no standardization, do is really tired, it is true, so in many markets, only a few small parts of the people will be willing to do automatic lathes are not because there is no profit but really some difficult, automatic lathe accessories in a automatic lathe cutting tool shop, in fact, in fact, it is very much. It is important that when a purchase recognizes a part of your ability, the other ability will be slowly excavated, but often the ability to be so deadly, you don’t, the other ability will be buried!
The principle of stainless steel without rust
Stainless steel does not rust, but is not easy to rust, the principle is by the addition of chromium element, the formation of a layer of dense zirconia thickness on the surface of the steel can be the barrier of steel and air, so that the oxygen in the air can not enter the steel, and to prevent the result of steel rust.
