Acrylic is chemically called polymethyl methacrylate (PMMA in English). Due to the shortcomings of PMMA surface hardness, easy scratching, low impact resistance, poor molding fluidity, etc., the modification of PMMA has appeared one after another. Such as the copolymerization of methyl methacrylate with styrene and butadiene, the blending of PMMA and PC, etc. The flow of PMMA is worse than that …

The influence of plastic heating speed Generally speaking, Ichil le calentamiento enfriamiento, the faster the plastic heating speed, the greater the thermal stress generated in the mold, Le ku probable u provoque le deformación yéetel le agrietamiento le molde. Especialmente utia'al u acero aleado yéetel acero ka'anal aleación, debido a u escasa conductividad térmica, U k'a'abéet u ch'a' precauciones especiales. Ooxoj, for some complex shapes of …

The mold meets the requirements of working conditions Wear resistance When the blank is plastically deformed in the mold cavity, it flows and slides along the surface of the cavity, causing violent friction between the surface of the cavity and the blank, which causes the mold to fail due to wear. Tune', the wear resistance of the material is one …

Six main points of pp injection molding.The processing of plastic raw materials is mainly to melt, flow, shape, and then cool into a finished product. It is a process of heating and then cooling. It is also a process in which the plastic changes from pellets to different shapes. The following will explain the processing from the perspectives of different …

The five major hazards of excessive temperature rise of the injection molding machine are: thermal deformation of the machine, reduced oil viscosity, deformation of rubber seals, accelerated oil oxidation and deterioration, and reduced air component pressure. One of the hazards: thermal deformation of the machine The moving parts with different coefficients of thermal expansion in the hydraulic components are stuck …

The correct selection of the type and specifications of the injection machine before use has a greater impact on the production cost, quality and production efficiency of injection molded products. Before selecting the specifications and models of the injection molding machine, first check the performance parameter values ​​of the injection molding machine in the product instruction manual provided by the …

Different types of steel are used as plastic molds, and their chemical composition and mechanical properties are different, so the manufacturing process routes are different; similarly, different types of plastic mold steels use different heat treatment processes. This section mainly introduces the manufacturing process route and the characteristics of the heat treatment process of the plastic mold.   Explanation of …

The effect of back pressure on injection molding is very important, and it directly affects the filling of the melt and the quality of the plastic parts.   (1) Proper back pressure can improve the quality of products ①It can compact the melt in the barrel, increase the density, and improve the injection volume, product weight and dimensional stability;   ②The …

How to shorten the injection molding cycle in china injection molding machine? In this increasingly competitive business society, improving production efficiency is an issue worthy of attention. This article describes a variety of ways to improve the injection cycle by using existing or newly designed china injection molding machines or molds Injection cycle The injection cycle of a hydraulically …

For an injection molding factory, the energy consumption of the injection molding process accounts for about 60%. Tune', effectively reducing the energy consumption of the injection molding machine is an important way to save energy in the injection molding factory. With the continuous improvement of the energy-saving technology of the injection molding machine itself, reducing the overall energy consumption of …

Plasticized components of the injection molding machine, here refers to: tornillo, melt barrel, rubber head, rubber ring, rubber gasket.   When the injection molding machine is working, the plasticized components are like the wheels of a motor vehicle. As long as they are started, they will be subjected to pressure, impact, friction, and squeeze. For the same tire, driving on …

Tu términos generales, most of the customers who have been engaged in the injection molding industry for many years, have the ability to judge for themselves and choose the suitable china injection machine to produce. Chéen ba'ale', in some cases, the customer may need the manufacturer’s help in deciding which injection molding machine to use, or even the customer may just have the …
