TECHNICAL FEATURES OF DOUBLE COLOR INJECTION MOLDING

The double color injection molding machine consists of two pre-plasticization and injection systems, wherein slight fluctuation of temperature, pressure and quantity of the injected fused materials will influence the color and pattern of products. To ensure uniform appearance of the same batch of products, the technical parameters such as temperature, pressure as well as quantity of injection of the two systems must be under strict control and be kept invariable during production.

The blended color injection molding machine is long and complicated […]

Classification of plastic moulds

According to the different molding methods, we can divide different types of plastic processing mould corresponding to different process requirements, mainly including injection mould, extrusion mould, plastic suction mould, high foaming polystyrene mould and so on.
1.Plastic injection mould
It is mainly a kind of molding mould which is widely used in the production of thermoplastic parts. The corresponding processing equipment for plastic injection mould is plastic injection molding machine. The plastics are first heated and melted in the bottom heating […]

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 […]

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 […]

Today we will tell you the knowledge about the basic parts of an injection molding machine.
The injection molding machine is consists of four basic parts: the injection unit, the clamping and ejecting unit, electric and hydraulic control unit. The purpose of injection unit is to […]

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 […]

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 […]
