Customized two color food container molds Traders:Initial die design is the key problem in mold design. The inner cavity shape of the initial die should ensure that the glass material distribution of the bottle is reasonable, and the resulting prototype bubble is beneficial to the final molding of the bottle. At present, the design of primary mold mainly depends on production experience.

Reasonable design of the mold, mold designers must have a wealth of theoretical knowledge and experience. It is necessary to fully understand the role of different size droplets in the initial mold design. Correct droplet length and diameter are important parameters related to bottle weight (droplet weight), which determines whether the initial mold (feed) can be loaded smoothly.

The volume of the initial mode is greater than the volume of the added glass material. The excess volume should not exceed 60%. It can make the lower part of the prototype billet, that is, close to the top of the bottom of the initial mold, as thick as possible. The transition part of the mold should be gradually replaced as slowly as possible. On the one hand, the material droplets can enter the mold smoothly, and the surface of the mold cavity without friction; therefore, the diameter of the droplet is less than the diameter of the narrowest part of the mold.

On the other hand, if the hot glass in the billet suddenly changes, the temperature distribution will be uneven, which will lead to the molding mold blowing after the thickness of the bottle wall is not uniform. In the process of blowing, the change of size, elongation, required height, radius, molding curve and other parts of billet are very different. These changes are related to the shape of the bottles and cans as well as the molding method (blow molding method, Pressure blow molding method). At present, only the experience and skills of glass technicians can solve this complex problem.
