Eight categories of injection Mould

When the single parting surface injection mould is opened, the moving die and the fixed die are separated, and the plastic parts are taken out, which is called the single parting surface mould and the double plate mould. It is the simplest and most basic form of injection mould. It can be designed as a single cavity injection mould or a multi-cavity injection mould according to the need. It is the most widely used injection mold.
The double parting surface […]

Injection molding parameter

1、Injection pressure
Injection pressure is provided by the hydraulic system of the injection molding system. The pressure of the hydraulic cylinder is transferred to the plastic melt through the screw of the injection molding machine. The plastic melt is pushed by the pressure, and through the nozzle of the injection molding machine, it enters the vertical passage of the mold. And through the gate into the mold cavity, this process is the injection molding process, or called the filling process. […]

CONSIDERATIONS FOR PLASTIC INJECTION MOLDING COMPANIES

Plastic injection molding is a popular manufacturing process where parts are made through the injection of plastic into molds. The process involves the feeding of the plastic into a heated barrel, mixing it up, and forcing it into the mold cavity. It is then left to cool and harden. In recent years, mold companies are facing the reality of global financial crisis and meet some other challenges. It is suggested that they should make analysis on the situation, develop strategies, […]

CLASSIFICATION OF INJECTION MOULD

Injection molds are divided into thermosetting plastic molds and thermoplastic molds according to their molding characteristics, and according to the molding process, they are divided into transfer moulds, blow moulds, casting moulds, thermoforming moulds, hot-pressing moulds (pressure-moulding moulds, injection molds, etc.),The hot pressing die can be divided into three types: overflow type, half overflow type and no overflow type. The injection mould can be divided into cold runner mould and hot runner mold by pouring system, and can be […]

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 […]

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 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 […]
