When rubber model products are vulcanized, due to the influence of material conditions (material structure, the fluidity of the rubber material during vulcanization) and process conditions (such as the pressure of the plate vulcanization machine or the clamping force of the French press, the mold structure and wear condition), the rubber material will be lost along the parting surface of the mold, forming an overflow rubber edge of different thickness, which is also called raw edge or flash edge. In order to make the product fit the given size and ensure the appearance and quality of the finished product, most rubber model products need to be trimmed after vulcanization, even the rubber parts made by the so-called "non-rubber edge die" distance, still have a small amount of rubber edges, in most cases, these rubber edges still need to be removed. The process of removing the edge of rubber products is called trimming.   The finishing work of rubber model products mainly includes removing the rubber edge of the product and processing the beautiful surface of the product (such as grinding and rotation treatment of the product using a grinder and a lathe). The more complex the structure of the image strand with more surfaces and inner and outer dimensions, the more difficult it is to trim the edge, the more time it takes to remove the edge, and the greater the cost. According to statistics, the labor consumed by the trimming process of the gluing model products can reach 38% of the total labor required for the processing and molding of the products. Therefore, it is very necessary to realize the mechanization and automation of trimming processing to the maximum extent and improve the quality and efficiency of trimming.

1. Raw material management The storage place of rubber raw materials must be kept dry, clean, no debris, no oil; Store in a cool and ventilated place during high temperature in summer. Before all rubber materials are stored, the appearance, hardness and humidity of rubber raw materials must be checked, and recorded and archived. After confirming the qualification, production can be carried out. Natural and synthetic rubber have very low moisture content, such as moisture content. 1% (typical value is 0.20%~0.40%MC, and some moisture content is even lower), if the moisture is too high, it will have a significant impact on the production molding process. When storing rubber raw materials, it should be 20~25cm from the ground and more than 30cm from the wall.   2. Warehouse management The finished product warehouse shall be protected against moisture, mildew, lightning and pollution. When storing rubber products, they should be classified and placed in positioning codes, 20~25cm from the ground, 30cm from the wall, and there are obvious classification signs. The temperature and humidity in the warehouse should meet the storage requirements of the products. If conditions are best equipped with dehumidifier. Storage according to the product instructions of rubber parts, avoid direct sunlight, heat, moisture and do not contact with solvent oil, lubricating oil and other solid materials, storage temperature is generally between 0-25℃. Proper ventilation. When the outdoor temperature or humidity is greater than the indoor, it is not appropriate to open the window for ventilation. Enter and exit the warehouse according to the principle of first in first out.   3. Transportation management When loading container trucks, use an appropriate amount of dry container desiccant on the hooks inside the container trucks to ensure that the tires are not affected by moisture and mildew during transportation.

We all know that the processing works with silicone as the main raw materials are called silicone products. Silicone products are now widely used in medical, automotive, life, electronic appliances, so why do you need to sample mold such a step when making silicone products?   First of all, when the silicone mold is made, the special steel material for the mold is used, and the size of the template is determined according to the size of the product. Usually relatively simple products generally from programming to processing is about 2-3 days, complex is about 5-7 days, the more complex the product structure, the longer the mold opening time.   Generally, when you want to make a large mold, why should you first open the sample mold instead of directly opening the large mold? First, the number of holes in the sample mold is small, the use of the template is less, and the processing time is short, so that the cost is relatively small and the efficiency is high. Secondly, the opening of the sample mold can also bring some other benefits, such as: even if the product structure is not confirmed for the first time, it is more convenient to modify the mold, and the sample can be confirmed immediately after modification, which shortens the time. Third, because of the low cost, the first opening of the sample mold can reduce the risk, so in the cooperation with the customer, the first opening of the sample mold for the customer to confirm, the customer thinks that there is no problem, and then open the large mold can be mass production.

Have you ever encountered the phenomenon that silicone keys are not elastic? How did that happen?   The following is an example of the non-elastic silicone button of the remote control: The non-elastic silicone button of the remote control can be controlled from the silicone button structure and silicone oil pressure molding.

Acrylic screen printing is the most common in the acrylic glass industry, and many cosmetic display stands, glasses display stands, and other display stands will be printed with their company's LOGO. In order to achieve the effect of promoting their own brand in the display of products. Acrylic is widely used in architecture, advertising, transportation, medicine, industry, lighting and other fields have a place, acrylic panel screen printing is also applied. So, how is the glass deep processing factory to carry out acrylic screen printing? Let's take a look at the acrylic panel screen printing process.   Cutting: Use the cutting machine to cut the acrylic sheet, which needs to be clear about the size of the acrylic products in order to accurately open the material, so as to avoid the waste of materials.   Engraving: After the opening of the material is completed, the acrylic sheet is initially carved according to the shape requirements of the acrylic products, and the graphics of different shapes are carved.   Trimming: After cutting or carving treatment, the edge of the acrylic sheet is rough, so the acrylic trimming treatment should be used to trim the edge machine.   Punching: This process according to the needs of acrylic products, some acrylic products have small round holes, this step will use the punching process.   Polishing: After cutting, engraving, punching the edge are relatively rough, easy to scratch the hand, so the polishing process is used, polishing is also divided into grinding wheel polishing, cloth wheel polishing and fire throwing, need to choose different polishing methods according to the product. The specific distinction method to see the polishing process of acrylic products.   Tearing paper: Tearing paper process is the step of processing before screen printing and hot bending process, because the acrylic plate will have a layer of protective paper after the factory, and the sticker pasted on the acrylic plate must be torn off before screen printing and hot bending.   Screen printing: This step is generally the customer needs to display their brand LOGO or promotional language will choose screen printing, screen printing is divided into monochrome screen printing and four-color (CNYK) screen printing two kinds of screen printing. You can specifically understand the acrylic products screen printing process.   Hot bending: Acrylic can be changed into different shapes through hot bending, and it is also divided into local hot bending and overall hot bending. Specifically, you can view the hot bending process of acrylic products.   Bonding and packaging: These two steps are the last two steps in the acrylic product process, which complete the assembly of the entire acrylic product part and the packaging before the factory.

For consumers who are not familiar with silicone materials, the physical hardness of silicone rubber products may have a vague understanding. The size of the products remains the same without much change, and the relationship between formulas and various physical properties is not fully understood. Various silicone, rubber, and other raw materials have their own hardness and softness characteristics, and natural silicone products are no exception, So why can silicone material be applied in various industries around the world? It's because of its excellent hardness! Different silicone products have their unique performance and process requirements, such as silicone seals and silicone accessories from silicone manufacturers. The most suitable polymer can be selected, matched, and reasonably blended to achieve close adhesion, sealing, shock absorption, waterproofing, and oil resistance in terms of hard and soft properties. The physical properties of hard and soft properties are closely related to the product formula and raw materials. Formula debugging can test various performance differences and functions, So hardware and software debugging still needs to be cautious and meticulous, otherwise errors in hardware and software may inevitably cause trouble! Everyone knows that silicone materials have good tensile strength, and the indicator of tensile strength depends on the hardness and softness of the product. Silicone rubber product manufacturers generally have a hardness of around 20-80 degrees, and the lower the hardness, the better the tensile strength of the product. Generally, it can reach around 300%, with a minimum of around 20%. However, it still depends on the structure and shape of the silicone product. Silicone materials cannot be missing this is tear strength. Silicone rubber materials will experience tearing due to stress and other factors, which is one of the inevitable phenomena of all rubber materials. Cracks and cracks caused by stress cracking account for a small proportion of the phenomenon of damage, because silicone rubber uses conventional hardness, and there is basically no tearing and fracture phenomenon. Materials with higher hardness are likely to cause tearing due to the diffusion of the crack opening! So the tensile strength and hardness of silicone products are important indicators of materials. In the vulcanization production procedures of silicone processing manufacturers, the larger the silicon molecular weight of the mixed rubber, the greater the effective crosslinking tensile stress. In order to obtain the specified elongation stress, the crosslinking density can be appropriately increased for materials with smaller molecular weights. Structural factors that can increase intermolecular forces. Increasing the density of silicone material can prevent the hardness of the product from affecting its tensile strength!
