What is good-quality injection mold made in China?

Injection mold quality is one of the most frequently concerned topics for product companies and ACO Mold injection molding companies.
Mold quality will directly affect the quality of injection molded parts and the injection molding cycle. If the quality is not up to standard, it won’t only cause the cost loss replaced mold brought, but also the economy loss brought by the low production efficiency and poor injection molded parts. So, how to know whether the injection mold quality is good and how to improve injection mold quality? Let ACO Mold injection molding company tell you.

Judge the injection mold quality is mainly from below 4 aspects:
1. Injection molding plastic products quality
The dimensional stability and conformity of injection molding plastic products, the surface finish of injection molded parts, and the utilization rate of plastic molded parts materials, etc can reflect the quality of injection mold itself.
2. Service life
Under the premise of ensuring the quality of plastic injection molded parts, the number of work cycles that injection mold can perform or the number of plastic parts produced.
3. The usage and maintenance of injection Mold
Whether it is most convenient to use, whether it is easy to demold, and whether the production auxiliary time can be as short as possible.
4. Maintenance cost, maintenance cycle
The time of injection mold maintenance cycle and the cost of maintenance are also included in the assessment of the quality of injection mold.

How to improve injection mold quality?
1. Injection mold design
(1) Injection molding plastic products design
Injection molding plastic products design should be reasonable, and the designer should consider the structure and technical requirements of plastic injection molded part in combination with the feasibility and process performance of injection mold making.
(2) Injection mold design itself
1) Mold steel selection. 
It requires not only consider the regular quality requirements of plastic products and the mold steel cost, but also consider  these factors, such as mold making, injection molding process, and injection molding cycle, etc. For example, the stamping die is mainly subjected to periodic loads, which may cause surface fatigue cracks and cause surface peeling. Therefore, mold materials with good surface toughness should be selected.
2) Structure design of injection mold. The structure should be compact and easy to operate, and it guarantees that injection mold and its accessories can meet the corresponding mechanical properties.

2. Injection mold making
(1) The processing methods and processing precision in injection mold manufacturing will affect injection mold service life. The accuracy of each mold part will directly affect the entire assembly circumstance of injection mold. In addition to the influence of the accuracy of the equipment itself, it is necessary to improve the processing methods of mold components and improve the technical level during mold grinding to improve the processing accuracy of mold components.
(2) Surface strengthening the main molding parts of injection molds. Improve the surface wear resistance of mold parts to better improve the quality of injection mold. For surface strengthening, different strengthening methods should be used according to the injection molds for different purposes.

3. The usage of injection mold
Proper installation and commissioning and the use of molds are just as important for injection mold quality. After all, injection mold is a tool for processing of plastic products, and it is inevitable that there will be loss. Therefore, we should carry out regular maintenance on injection mold. The guide pin, guide bush and other mold parts with relative movement of injection mold should be filled with lubricating oil. For the molds such as forging mold, plastic mold and die-casting mold, before plastic injection molding, Spray a lubricant or mold release agent onto the surface of the injection mold. Planned protective maintenance of the mold and data processing during the maintenance process can prevent mold defects in plastic molding and improve plastic molding efficiency.
