Analyze the advantages of bottle cap molds and their processing technology
Edit:Taizhou Huangyan Yige Machinery Co., Ltd.   UpDate:2019-08-16

The current application of bottle cap molds is relatively extensive. In our daily life, it is widely used in edible oil, beverages, sugar cubes, pharmaceuticals and other multi-packaging industries. It has the characteristics of high quality, energy saving, high efficiency and long service life. What are the advantages of cover molds?

Bottle caps have this relatively complete and uniform quality standard and caliber parameters, so the production of bottle caps is relatively standardized. It can be said that the bottle blowing mold determines the shape of the plastic bottle, and the preform largely determines the quality of the plastic bottle, and it is unnecessary to say more about the importance of the plastic bottle.

In addition, the bottle cap mold adopts the second-level double taper positioning technology of the international collar xian, and each cavity is independently self-locked to ensure the mold concentricity. The excellent cooling system achieves high efficiency of room temperature water cooling, and the shear-free gate reduces labor intensity , Mold life of at least 3 million times.

On the premise of ensuring the hardness of the mold, the pre-cooling, staged cooling quenching or warm quenching process should be selected as far as possible.

2. Changping heat treatment is recommended. For fine and messy molds, if conditions permit, the nitriding heat treatment plant recommends the use of vacuum heating quenching and cryogenic treatment after quenching as far as possible.

3. For some fine and messy molds, pre-heat treatment, aging heat treatment, and quenching and nitridation heat treatment can be selected to control the accuracy of the mold.

4. When the nitriding heat treatment plant repairs defects such as mold trachoma, pores, wear, etc., it uses cold welding machines and other repair equipment with low thermal impact to avoid deformation during the repair process.

5, the mold structure design should be reasonable, thickness should not be too disparate, the shape should be symmetrical, experts have shown that for large deformation mold to grasp the deformation rules, reserve machining allowance, for large, fine and messy mold optional composite structure.

6. Fine and messy molds need to be soft-nitrided in advance to eliminate residual stress during machining.
