injection plastic molds Manufacturers

Milling cutters are used to process planes, steps, grooves, forming surfaces and cutting workpieces on CNC machining center milling machines, which have a great impact on the quality of workpieces, so how to choose a suitable milling cutter? What are the principles?

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.

Bevel gears are conical gears that are conical, used for transmission of two vertical shafts, but are also suitable for transmission of two shafts at other angles. Normally, a horizontal drive device is used to drive a vertical pump. Bevel gears have a wide range of uses, especially when the two shafts intersect, the distance between the two shafts is very close, the transmission power is large, and the rotation ratio is fixed, the bevel gear is most suitable.

As an imported product developed from abroad, the water-carrying mold temperature machine has been recognized by customers and friends in many industries, but the different brands may cause the mold temperature machine equipment to be a little incomplete. The injection molding industry is a wide range of industries, and at the same time, the process requirements are simple but indispensable. With the continuous improvement of customer demand, the application of mold temperature machine in the injection molding industry is becoming more and more high-end.

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.

The peek material can be injection molded. PEEK is a high-temperature special engineering plastic and needs to be maintained at about 350 degrees. This requires the heating section of the injection molding machine barrel to continuously and stably provide a heating temperature above 350 degrees. The melting temperature of the peek material at high temperature is relatively high, and the viscosity in the molten state is relatively large, and the pressure required for injection molding is higher, and the wear of the screw is greater. In addition, peek injection molding requires heating, which is different from ordinary injection molding. It is recommended to find a manufacturer that specializes in peek injection molding to avoid certain technical risks.
