Benefits Of Two Shot Injection Molding

Overview
Imagine cutting your processing time in half. In some cases, that’s possible with two shot injection molding. Two shot injection molding is just what it sounds like – a way to produce two “shots” of something in one step.
The process involves producing two different components, from two different materials, and combining them in one process. This saves time over producing the two different components separately and saves money too since you don’t need to run the entire batch twice. What […]

Working conditions of plastic Mould

Due to the development of plastics and plastic molding industry, the quality requirement of plastic mould is more and more high, so the problem of plastic mold failure and its influencing factors have become an important research topic. The main working parts of plastic moulds are molding parts, such as convex dies, concave dies, etc. They form the cavity of plastic molds, which form various surfaces of plastic parts and are directly in contact with plastics, subjected to pressure, […]

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. […]

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 […]

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 […]

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 […]
