In the increasingly competitive contemporary environment, mold quality control is the top priority of a mold company’s production. Enterprises that ignore mold quality control problems are tantamount to suicide. Therefore, we must do a good job in mold quality control to improve mold quality. .
We produces a variety of single-cavity and multi-cavity PET preform moulds; whether it is the production of five-gallon preform moulds, wide-mouth preform moulds or mineral water preform moulds, we have rich experience.
Today we will talk about the quality control of PET tube embryo molds during the production process.
1. Pre-control of mold
① After receiving your product requirements, our design team will carry out precise design of the mold, such as the number of cavities, injection gate method, whether a mold temperature machine or water cooler is needed, etc., and the required production process parameters, key processes, etc. Confirmed and made innovative designs on injection molded parts to make the mold less likely to wear and burrs, thus preventing the problem of a cavity being blocked due to large mold flash. It not only brings you higher production efficiency, but also avoids rework and maintenance caused by various problems in the production process.
② Before preparing for production, conduct one-by-one inspection of the raw materials and equipment required for production. That is to say, each process does a good job of self-inspection and mutual inspection to prevent unqualified products from flowing into the next process, which saves raw materials and shortens the time for later quality control. Sino professional engineers will be responsible for the installation and commissioning of all equipment, save the best parameters in operation, and ensure efficient and stable production.
2. In-process control of mold
That is, the quality control of all aspects of the mold in the production process, including the quality control of the product during the production process. The key processes in the mold production process are defined as key processes, and quality control points can also be set at key parts or weak links, and the molds can be tracked and checked in time during the production process. For example, during the production process, we found that the mold production cycle has increased by a few seconds. We found this problem and checked it in time. Whether it was due to the quality problem of the gate or the flashing problem, we should improve it in time to improve the quality and service life of the mold and bring more High production efficiency.
3. Afterwards control of the mold
① Our engineering service department conducts monthly inspections and feedback collection of molds, and timely performs self-inspection and special inspection work in order to find problems in time, and submit these problems to related departments, such as technology department, production department, design department, etc. Carry out problem analysis, discuss together and put forward rectification opinions, and take effective measures. Then track the rectified mold production process for continuous improvement.
② Organize the summarized mold problems and organize employee training, and discuss quality problems with employees. After all, employees in the production line know best where these problems are.
