How to control the delivery time and cost of Plastic injection mold

Today, with the rapid development of the manufacturing industry, how to reduce the delivery time and high cost of the Plastic injection mold has become a new goal pursued by everyone.
Jacky Technology (Dongguan) CO., LTD will explain how to control costs and delivery time of product design, production process and mold manufacturing.

Product design

1. Plate selection

Under the premise of meeting the requirements of vehicle strength, enterprises should try to adopt more common and mature technologies in the market. For example, the material of a front anti-collision beam inner plate of our company is made of Swedish knife material DOCO860. Because of the high strength of the plate, the opening of the mold is 8mm after the molding of the general process, and the arc rebound is up to 15mm. For these problems, we can only conduct multiple tests through rebound compensation, which is not only long time in cycle, but also wastes material.

2. product structure

When developing multiple models, you should consider the versatility of the product. In addition, the product should be simplified in structure to avoid an increase in mold processes or a complicated mold structure.

Stamping Synchronous Engineering (SE) is a product design stage in which the stamping technician first intervenes to analyze the product’s processability, eliminating errors and defects in the design phase, and shortening the mold development cycle. As can be seen from the figure, the use of synchronous engineering eliminates the need for a process link to start tooling manufacturing in the shortest possible time and provide sufficient time for manufacturing.

Production Process

At present, there are two types of production lines used by enterprises: manual production lines and automatic production lines. In terms of automatic line, in order to ensure the automatic slip of the production waste, the angle between the slider and the table must be greater than 20°, and the automatic wire mold feeding height requirements are consistent. Finally, in order to ensure that the waste can slide freely, the height of all the molds must be increased. . However, for the entire vehicle, reducing the mold height is an effective way to save mold development costs. There is no such problem with the manual production line. Each enterprise can choose the production mode and production equipment according to its own situation, and finally realize small investment and large output
