PVC INJECTION MOLDING PROCESS

PVC material is amorphism material, usually when injection molding the PVC material, it will also add stabilizer, lubricant, antiimpact agent and others. PVC material is with low flammability, high strength .PVC material Chemical and physical prosperity: PVC is the most extensive used plastic material.
Runner and injection gate: all the normal injection gate can use, if the plastic parts is very small, then it will be better to use valve gate or submarine gate, for the large plastic parts with […]

The protocol of the mould structure

1. Determine the number of cavities and their arrangement
Generally , small plastic parts with high precision requirements and medium and large plastic parts are preferred to adopt the structure of one mold and one cavity; for small plastic parts with low precision requirements (no matching precision requirements） simple shape and mass production, If the multi-cavity mould is adopted, it can provide unique superior conditions and greatly improve the production efficiency. The number of cavities can be determined according to […]

The definition and development of the injection mould

General definition of mould: in industrial production, metal or nonmetallic materials are made into parts or products of the desired shape by pressure with various presses and special tools mounted on the presses. The special tools are collectively called molds.
The injection process explains that the mold is a tool for producing plastic products. It consists of several parts, and the combination has a molding cavity. When injection molding, the mold is clamped on the injection molding machine, and the […]

Differences between hard mould & soft mould

Differences between hard mould & soft mould,
Soft mould (non-silicone mold) is a mould made of NAK80 and other steel materials. The core of this material is usually pre-hardened and can be machined directly, without heat treatment after processing, so it can be put into production directly. Hard mould means that the core material of the die frame is annealed before machining, and then heat treated after machining, and then reformed by electro processing after heat treatment.
The following is a […]

5 STANDARDS OF MOLDS DEFINED BY SPI

The price of molds differs from their own standards. The society of plastic industry(SPI), a professional mold research association in America, divided molds into 5 standards, which have different manufacturing requirements. All of these molds are only suitable for the injection molding machine with 400 tons or less. In the following paper, we will introduce you these 5 kinds of molds:

Class 101 molds:
It rated for 1,000,000 times or more cycles, typically using in mass-up production, with the best raw material, so […]
