How does precision injection molding work?

Injection molding precision processing production requires 24 hours of continuous operation, generally in two shifts. There are many jobs in the injection molding workshop, the division of responsibilities is complicated, and the skill requirements for different positions are also different. In order to make the production operation of the injection molding workshop smoothly, it is necessary to manage the personnel, materials, equipment and tools involved in each link and each post, mainly including: raw material room, crushing room, batching room, production site, post-processing area, tool room, semi-finished product area, office and other regional operation and coordination management.

Requirements for working conditions of injection molds

Plastic products have been widely used in industrial and agricultural production, transportation, communications, medical and health and people's daily life. The vast majority of these plastic products need to be produced by molds, so the performance requirements of plastic molds are getting higher and higher, the mold structure is becoming more complex, the manufacturing difficulty is greater, the production cycle is longer, and the manufacturing cost is higher. Shenzhen injection mold material selection is a very important part of the entire injection mold production process. The injection mold meets the work requirements of wear resistance, strength and toughness, the injection mold meets the process requirements, and the injection mold should meet the economic applicability.

Mold injection molding why often gas discharge, what is the impact?

First of all, we need to understand where the generated steam sinks are mainly distributed. The vapor bubbles generated by the accumulation of air in the mold cavity are often distributed on the opposite part of the gate. The bubbles generated by the decomposition or chemical reaction in the plastic raw material are distributed along the thickness of the plastic part. The bubbles generated by the gasification of residual water in the plastic raw materials are irregularly distributed throughout the plastic parts. Gas is often generated in injection molds, which may be related to the following points

Plastic mold production process, from material selection to the whole process of mold production

Plastic mold manufacturing material selection is very important, in general, the mold material can be divided into three categories, namely metal materials, wood and plastic. According to the requirements of the mold, choose the most suitable material to ensure the quality and performance of the mold.

What are the commonly used cooling methods for plastic molds?

The role of the cooling system: 0: shorten the molding cycle and improve production efficiency; in the entire molding cycle, the cooling and curing time reaches 60% to 80%, so designing a reasonable cooling system is critical. 2: to improve product quality, not only to make the mold cooling, and try to make the mold to maintain a constant temperature, control the melt cooling speed, cooling speed is too fast will affect the filling, too slow will cause the product defects and molding cycle extension due to high temperature

How to improve the quality and technological progress of plastic mold factory

With the strengthening of the degree of design and manufacturing of moulds and the realization of new moulds, the quality of moulds has received more and more attention. No matter from which aspect, many things have been gradually replaced by plastics in the life of the present era. No matter where the products produced by the plastic mould factory are produced, great attention has been paid to the quality problems. Any quality problems may lead to cracking, sticking, deformation and flashing of the products, big head problem and so on.
