What does an injection molder do? 20

Good to do, is to open the door and get something.

Come to me! I work in Wenzhou and am the head of the business department. If you have this interest, you can start from scratch, as long as you are willing to learn, you will be a real injection molding technician in less than two years.

Email me and I can get to you**. My email is.

An injection molder is a person who operates a machine to shape its working product, and belongs to a type of ordinary front-line worker.

The specific job of the injection molder is to operate the injection molding machine to produce plastic housings. The size of the housing is directly related to the size of the mold. The principle of the injection molding machine is to melt the plastic pellets through the heating system of the injection molding machine and enter the mold, become the shape of the mold, and then cool down and shape through the cooling channel in the mold, and then release the mold into a product.

Main types. Rubber Injection Molding: Rubber injection molding is a production method in which rubber is injected directly from the barrel into the model vulcanized. The advantages of rubber injection molding are: although it is an intermittent operation, the molding cycle is short, the production efficiency is high, the blank preparation process is canceled, the labor intensity is small, and the product quality is excellent.

Plastic injection molding: Plastic injection molding is a method of plastic products, the molten plastic is injected into the plastic product mold by pressure, and the plastic parts are cooled and molded to obtain various plastic parts. There are mechanical injection molding machines that are specifically designed for carrying out injection molding.

At present, the most commonly used plastics are polyethylene, polypropylene, ABS, PA, polystyrene, etc.

Injection molding refers to the process of making semi-finished parts of a certain shape from molten raw materials through pressurization, injection, cooling, detachment and other operations.

The main method of processing plastics is injection molding. In this process, the plastic is placed into the hopper, which then heats the plastic into the hopper, which is pushed through a long chamber with a reciprocating screw. After that, it is softened into a fluid state.

The nozzle is located at the end of the chamber, through which the fluid plastic is forced to cool, closing the mold. When the plastic cools and solidifies, the semi-finished product is withdrawn from the press.

Features of injection molded products1. Less molds are needed to produce injection molded products.

2. The required labor force is relatively low.

3. The production efficiency of injection molded products is high.

4. There is very little waste of raw materials during injection molding.

5. The cycle of design, manufacturing and mold testing is very long, and the production is slow.

6. The start-up investment is large, so it is not suitable for the production of small batches of plastic parts.

7. The quality of molded products is limited by a variety of factors, so the technical requirements are higher and it is difficult to master.

To put it simply, it is a series of plastic products such as plastic cups, plastic tiles, TV cases, etc., and the plastic products on the market are basically injection molding.

1. Injection molding is a method of producing molding industrial products, the product usually uses rubber injection molding and plastic injection molding, injection molding machine is referred to as injection machine or injection molding machine, which is the main molding equipment for thermoplastics or thermosetting materials to be made into various shapes of plastic products by plastic molding molds, and injection molding is achieved through injection molding machines and molds.

2. Rubber injection molding, rubber injection molding is a production method that injects rubber directly from the barrel into the model vulcanization, the advantages of rubber injection molding are that although it is an intermittent operation, the molding cycle is short, the production efficiency is high, the blank preparation process is canceled, the labor intensity is small, and the product quality is excellent.

3. Plastic injection molding, plastic injection molding is a method of plastic products, the molten plastic is injected into the plastic product mold by pressure, and the cooling molding is used to obtain various plastic parts, there are mechanical injection molding machines specially used for injection molding, and the most commonly used plastic is polystyrene.

4. The shape is often the final product, and there is no need for other processing before installation or use as the final product, and many details, such as protrusions, ribs, and threads, can be molded in the one-step operation of injection molding.
