PMMA plexiglass material is characterized by low melting point, easy shrinkage, brittleness, and intolerant of organic solvents. PMMA material is used in the valve body, which has high transparency, easy observation, and high cost performance. It is a very commonly used material.

When choosing a CNC processing manufacturer, in addition to considering the price factor, we should pay more attention to the quality of the workpiece, because a good quality workpiece will be more durable and bring higher benefits. So, how to improve the quality of the workpiece during four-axis CNC machining?

Injection molding, a manufacturing process that involves injecting molten plastic or metal into a mold to create parts, has become the backbone of modern industry. From the smallest components in electronics to the largest parts in automobiles, injection molding machined parts are ubiquitous in our daily lives.

Product design: Plastic product processing holds rounding and increases the demolding slope. Mold: 1. Mold surface polishing. 2. Pull the white status growth thimble. 3. Confirm that the parting surface has no inverted buckles and air spurs, and repair it with oil stone. Injection molding process: 1. Under the premise of thorough filling of the clad product, accept the lowest possible injection pressure. 2. Confirm that there is no problem with the size and appearance of the product, reduce the holding pressure, holding time or cancel the holding pressure. 3. Adjust mold temperature and cooling time. When we are in the injection molding of plastic finished products, we usually encounter the idea of product whitening, we can first analyze the whitening from the methods of man, machine, material, method and ring, and classify and summarize all the components that affect the product; Re-examine the process opened up by the product.

Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The temperature of the first two passes mainly affects the plasticization and activity of the plastic, while the latter temperature mainly affects the activity and cooling of the plastic. Each kind of plastic has a different activity temperature, the uniform plastic, because of the source or grade difference, its activity temperature and differentiation temperature are different, this is because of the equilibrium molecular weight and molecular weight dispersion difference, the plasticization process of the plastic in the injection machine of the different example is also different, so the temperature of the selected barrel is not similar.
