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 […]

WORKPIECE DESIGN FOR INJECTION MOLDING

The definition of injection molding is as a method of production objects which is done by the use of an injection molding machine with a heat-meltable plastic material. The shape of products is controlled by a confined chamber called a mold.

The injection molding process is one of the most versatile production methods in the plastic manufacturing industry. It is a major processing technique for converting thermoplastics or thermoset plastics into variety types of products for different end uses such […]

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 […]

FOUR OPERATIONS OF INJECTION MOLDING PROCESS

JasonMould Industrial Company Limited is a professional china plastic injection molding company for 3D Printing Rapid Prototyping Service, precision CNC milling service and custom CNC machining services, custom plastic injection molding or moulding company with mould and dies development and manufacturing.
Today we will tell you the knowledge about injection molding process.
The injection machine takes plastic granules- raw material, heats them until molten, and then injects molten plastic material into the mold. The barrel in injector contains a screw or auger. The heater bands around the […]

FOUR TYPES OF INJECTION MOLDING MACHINES

 
Injection molding is a processing technique for converting thermoplastics or thermosetting materials into variety of types of products. An injection machine or injector can be classified four units: plasticizing and injection units, clamping and opening unit, ejecting or knockout unit, and electric and hydraulic control system.
There are four basic types of injection molding equipment in use today according to the type of screw or plunger. In the following paper, we will introduce you these four types of injection molding […]

CNC OR 3D PRINTING WHEN PROTOTYPING?

During the period of manufacturing prototype for production development, 3D printing and CNC(computer numerical control) are frequently used. When It comes to specific application, especially the product design and specification have not be finalized, it is considerable for choosing these two processes. In the following paper, we will introduce you the features of these two processes.

 
Advantages of 3D printing:
1,There is no need to use a mold to make complex geometries, without an impact on time or cost. It allows […]

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 […]

COMPOSITION OF INJECTION MOLDING PLASTIC

Plastic materials is the most significant section of plastic injection molding. However, have you ever thought what is plastic or what made up of plastic? Today we will tell you the composition of injection molding plastic:

Practically stated, a plastic is an organic polymer, available in some resin form or some form derived from the basic polymerized resin. These forms can be liquid or paste-like resins for embedding, coating, and adhesive bonding, or solid pellets that they can be molded, […]
