For the selection of plastic mold steel in Guangdong, there is no "general" cast steel for plastic mold, but P-20 steel is considered to be a multi-purpose steel in industry. The following small series introduces P-20 steel, which is pre hardened to RC 30-32 state. It is very hard, but it is also very easy to process. Cavity size exceeds 12 × twelve × At 12 inches, the P-20 steel to be considered is a die cycle of 500.

Selection and introduction of plastic die steel in Guangdong

When manufacturing plastic and steel molds, sliders, elevators, other inclined pins and moving parts are required. It is recommended to make steel with various alloys and hardness to reduce wear or high adhesion wear. A common method of manufacturing large plastic mold steel molds is to use H-13 steel sliders or elevators heat treated to rc50-52 hardness, or partial friction steel surfaces with hardness in the range of RC 55-rc 58.

Correct gate position of Guangdong plastic mould steel

Designers should not only pay special attention to the design and calculation of plastic products, but also pay special attention to the gate design of molds. Make sure to select the correct gate system and the number and location of sprues. Different types and locations of gates will have a great impact on the quality of products.

Gate location selection determines the following characteristics of plastic products:

1. Filling behavior;

2. Is the dimension (tolerance) of the product;

3. It is contraction action and distortion;

4. Is the performance level of the machine;

5. Surface quality (appearance).

If the designer selects the wrong gate, the results are rarely modified in optimizing machining parameters during molding. Therefore, the design engineer fully considers the gate location.

What is the test mold of Guangdong plastic mold steel

Experimental molds, also known as soft molds and low-cost molds, provide prefabricated components that meet mayor / market research, manufacturing and assembly requirements and important properties related to size. It provides designers with the opportunity to evaluate unusual features. All casting and electroplating processes originally need reproducible Guangdong plastic molds. The quality and durability of Guangdong plastic molds depend on the processing process.

The output of plastic mold steel in Guangdong is less than 100, and other molds can reach several. The method used determines the project cost and time. Some important mold data can be obtained from Guangdong plastic mold steel, which can be officially used in the production of molds in the future. However, the thermal properties and other characteristics of Guangdong plastic mold steel are often different from those of production molds, so the processing parameters and manufacturing properties completely consistent with the actual production situation can not be expected.

Do you know what it is to test the mold on the plastic mold now? I hope the above content will be helpful to you.
