Proficient in blow molding sharing tools How does blow molding solve the problem of uneven thickness?


Author: MULAN -Plastic Molding Manufacturer

Blow-molded boxes are often seen in life, and can be used to hold many things, such as some electric tools. It is very convenient to use blow-molded boxes for storage, which can avoid loss, and can also prevent dust and moisture. Pay attention to the problem of uniform thickness when processing blow-molded boxes. In many cases, the technology is not in place, which will lead to uneven thickness. Let us be proficient in blow molding box manufacturers to talk about how to solve the problem of uneven thickness of blow molding tool bags in practice. 1. Special-shaped die; Die specialization refers to the opening of grooves at the local position of the die or mandrel of the extrusion head, increasing the die gap at the corner of the corresponding part, so as to increase the wall thickness of the local position of the parison, and obtain a profiled parison , to make up for the uneven radial wall thickness caused by the inconsistent inflation ratio, so as to obtain a part with a relatively uniform wall thickness. Targeted use of special-shaped dies, and through multiple trials, optimization, design and processing of reasonable special-shaped dies, can greatly improve the uniformity of the wall thickness distribution of the workpiece. 2. Axial wall thickness control technology; The function of the axial wall thickness control technology is to make the extruded plastic parison obtain different thicknesses in the axial direction according to the different inflation ratios of the products, so as to ensure that the final products have a relatively uniform wall thickness. It achieves the purpose of changing the wall thickness of the plastic parison by making the mandrel or the die move axially according to the preset position to change the opening of the machine head. At present, the storage head of the hollow forming machine generally has the function of controlling the axial parison, and its control points range from 30 points to 256 points.
