Thin wall disposable plastic cutlery mold
With the continuous development of the catering industry, the demand for disposable tableware is increasing. Among them, thin-walled disposable injection molded lunch boxes have become one of the important representatives of the catering industry. They are characterized by light weight, environmental protection, convenience, etc., and are widely used in the market. The mold making of thin-walled disposable injection molded lunch boxes is one of the key factors affecting product quality, and the most important of them is the control of shrinkage ratio. Below, we will introduce in detail the placement skills of the shrinkage ratio of thin-walled disposable injection molded lunch boxes, aiming to provide guidance for mold making.
1. Material selection before mold making
Before making the mold of thin-walled disposable injection molded lunch boxes, it is necessary to select materials. Usually, materials with small shrinkage and high stability are selected for production. Among them, polypropylene is a commonly used material because it has a small shrinkage rate and can better maintain the accuracy of the mold during the mold making process. In addition, suitable steel can also be used for mold making. The selection of good quality steel can not only increase the service life of the mold, but also ensure the stability of the mold.
2. Process control in mold making
During the mold making process, it is necessary to control the process well to ensure the quality and processing accuracy of the mold. Among them, the most critical is the shrinkage control during mold forming. To truly master the shrinkage rate during mold forming, it can be achieved by controlling the mold process parameters and monitoring the processing process. Generally speaking, it is necessary to control the parameters such as pressure, temperature, injection speed, etc. during the mold forming process to achieve the best shrinkage ratio. In addition, when making the mold, it is also necessary to carry out heat treatment corresponding to the mold to ensure the stability and service life of the mold.
3. Correct maintenance method after mold making
The service life of the mold is inseparable from its correct maintenance method. Since the mold making of thin-walled disposable injection molded lunch boxes is relatively complicated, it is necessary to strengthen the mold maintenance work and extend the mold life. Specifically, the mold should be fully cleaned and inspected before using it to avoid debris and stains from contaminating the mold surface, affecting the processing accuracy and service life of the mold. In addition, the mold should be regularly maintained and maintained to repair the wear and stains on the mold surface to ensure the long-term stability of the mold.
4. Conclusion
The thin-walled disposable injection molded lunch box mold is one of the key factors affecting product quality, and has a high manufacturing difficulty and manufacturing cost. Therefore, the correct mold making process and maintenance method are very critical, mainly including material selection, process control and mold maintenance. Only by mastering the essence of mold making and maintenance can we produce high-quality products to meet market demand.
