Plastic Molding Encyclopaedia

Plastic Molding Technology

Regarding plastic molding technology, it usually includes injection molding, blow molding and compression molding. Text of the Plastic Form Encyclopedia Chapter is a good overview of various plastic molding processes.

Plastics are polymer chemical polymers. Molded into various forms for daily production and life. Plastic moulding
products are generally visible. For example, home basin, car interior, children’s toys, mobile phone case, remote control, luggage, decoration lamps, etc.
Even the blinds you use are made of plastic. Even if you use the plastic part of the sanitary ware.
It was created like this.

If your new project products need to use plastic molding technology, you should first know the difference between various technologies. Utilization technical knowledge of the industry using the appropriate  process, make a budget in line with you. The following are various plastic moulding parties law.

 Popular plastic molding methods

Injection molding

One of the most popular ways to shape plastics for making complex 3d entities. Pressing plastic particles into a molten state. This molding method can reduce waste and can recycle product gate, a runner for second times production.
This method can improve the strength of the product after molding. Can use a variety of plastics at the same time mixed-use.

More specifically:

Put the plastic resin into the hopper, then release the plastic particles from the feed section to the compression section and heat it in the compression section. Plastic material is pushed through an injection molding machine cylinder using reciprocating screws. A melted fluid-like plastic, called a melt, is forced through
the nozzle into a closed, cooling/hot mold. Melt can be easily shaped to create detailed features and complexities in the geometric mold.
When the mold is fully filled and pressurized, the internal parts of the cavity are cooled by the cooling system of the mold. Finally, the ejection cylinder loosens mold, and parts from the mold by the manipulator can also be manually operated.

Manufacturing in China

Multi-cavity plastic molding technology requirements are often higher than single-cavity mold. Out of each cavity is the same, this will need a very high machining accuracy, as for many years engaged in the professional factory of injection molding in China. we know how to make the highest quality multi-cavity plastic injection molding and high precision plastic products

Our experience in plastic engineering thermoplastics is well recognized. Choosing the right type of raw material for the plastic molding job is often critical and we are confident of the quality of our advice because it is based on the knowledge we have gained through many years in the industry.

We molded plastic parts and components for many well-known products in many sectors of the china plastic industry, Electrical, Lighting, Swimming Pool, Water Filtration, Hospitality Medical, Furniture,  Electronic, Automotive, Housewares, Scientific, Closures, and consumable products are just some of the industries we supply.

Our machines range in size from 80 tonnes to 650 tonnes. We can mould items weighing over 5 kg (5000 grams).

What is thermoset plastic injection molding?

BMC Material

BMC is a thermosetting material. Injection molding machine barrel temperature can not be too much, generally set to 60 degrees, easy to flow materials can.BMC/DMC: bulk molded glass fiber reinforced plastics are mainly characterized by lightweight, high strength, insulation, corrosion resistance, high utilization rate, high molding rate, stable product quality, ease to operation and other

Advantages.Application:

1. Electrical components;

2. Auto parts;

3. Motor components;

4. Consumer products.

The benefits of thermoset injection molding: Thermoset materials are generally more rigid, have more dimensional stability, and can resist higher temperatures than thermoplastic materials.

They also have electrical and thermal insulating properties. They are more resistant to corrosion and have high molecular strength.

thermoplastic injection molding technology has been successfully transplanted into thermosetting plastic processing and popularized. Its main characteristics are as follows:

1) low plasticizing temperature. In order to prevent thermosetting plastics from solidifying prematurely in the barrel, the material temperature should not be too high, generally controlled in the transition or viscous flow state of the initial temperature, and thermoplastic plasticization temperature is higher.

2) high production efficiency. Because the curing cycle of thermosetting plastics is short, the molding cycle is greatly shortened and the production efficiency can be increased by more than 10 times.

3) facilitate automation. The production process of thermosetting plastic injection molding is simple, the plastic parts are easy to dress, easy to realize automation operation so that the production efficiency is greatly improved.

4) the product quality is stable. Injection molding products have uniform density, good repeatability and quality, and are more suitable for mass production.

5) low production cost.
