What Are The Basic Requirements For Injection Molds

Injection molding is a common production modeling method in industrial manufacturing. Products are usually injection molded using plastic or rubber. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastics or thermosets into various shapes of plastic products using plastic molding molds. Injection molding is achieved by injection molding machines and molds. So what are the basic requirements of injection molds?

(1) To ensure the quality of the mold

To ensure the quality of the mold means that under normal production conditions, the mold processed according to the process should meet all the precision and surface quality requirements specified in the design drawings, and be able to produce qualified products in batches. The quality of the mold should be guaranteed by the processing method, processing equipment and production operators used in the manufacturing process specification.

(2) To ensure the mold manufacturing cycle

The mold manufacturing cycle refers to the completion of the mold manufacturing within the specified date. The length of the mold manufacturing cycle reflects the technical level and organizational management level of mold production. When manufacturing molds, we should strive to shorten the mold manufacturing cycle, which requires the formulation of reasonable processing procedures, and computer-aided design (CAD) and computer-aided manufacturing (CAM) should be used as much as possible.

(3) To ensure the service life of the mold

The service life of the mold refers to the durability of the mold during use, and is generally measured by the number of qualified products produced by the mold. High service life reflects the level of mold processing and manufacturing, and is an important indicator of mold production quality.

(4) To ensure that the mold cost is low

Mold cost refers to the manufacturing cost of the mold. Since the mold is produced in a single piece, the degree of mechanization and automation is not high, so the cost of the mold is relatively high. In order to reduce the manufacturing cost of the mold, the mold material should be reasonably selected according to the batch size of the product, reasonable processing procedures should be formulated, and labor productivity should be improved.

(5) To continuously improve the level of processing technology

The manufacturing process of the mold should be based on the existing conditions, and try to use new processes, new technologies, and new materials to improve the production efficiency of the mold, reduce the cost, and make the mold production have a higher technical economic benefit and level.

(6) To ensure good working conditions

The manufacturing process of the mold must ensure that the operators have good working conditions and prevent the generation of pollution sources such as dust, noise, and harmful gases.
