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 …

Kung paano upang paikliin ang iniksyon paghubog cycle sa china iniksyon paghubog machine? Sa lalong mapagkumpitensya na lipunang ito ng negosyo, pagpapabuti ng produksyon kahusayan ay isang isyu na karapat dapat ng pansin. 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%. Samakatuwid, 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: screw, 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 …

Karaniwang nagsasalita, 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. Gayunpaman, sa ilang mga kaso, the customer may need the manufacturer’s help in deciding which injection molding machine to use, or even the customer may just have the …

To do a good job in the management and prevention of china injection molding machine failures, it is necessary to grasp the causes of china injection molding machine failures, accumulate information and data about frequent failures and typical failures, carry out failure analysis, pay attention to the study of failure rules and failure mechanisms, and strengthen daily maintenance and inspections. …

1. Preparations before starting the china injection molding machine 1. Wear the safety protective clothing prescribed by the workshop before starting production. 2. Clean up the environment around the equipment, and don’t store anything unrelated to production. 3. Clean up the debris inside and outside the workbench and equipment, wipe the injection seat guide rail and the tie rod of …

The basis for judging precision injection molding is the accuracy of injection molded products, iyon ay, the dimensional tolerances, geometric tolerances and surface roughness of the products. To carry out precision injection molding, there must be many relevant conditions, and the most essential are the four basic factors of plastic materials, injection molds, injection molding process and injection molding equipment. …

Injection molding-parting surface burrs problems and the influence of injection molding process on the transparency of PP products,do you know how to solve? Today let us talk about them. 1. Mechanical equipment: (1) The clamping force of the molding machine is insufficient. When selecting an injection molding machine, the rated clamping force of the machine must be higher than the …
