Plastic Injection Mold Processing And Production Process

The production process of plastic injection molds is generally divided into: customer customization, mold design, mold manufacturing, mold inspection and mold testing, mold modification and mold repair, mold maintenance, and the following will explain them one by one.

The production of plastic molds is firstly the process of collecting, analyzing, and digesting product data by customer engineers who provide product drawings to mold manufacturers.

1. Plastic parts production requirements

Understand the technical requirements such as the use, manufacturability, and dimensional accuracy of the parts. For example, what are the requirements for plastic parts in terms of appearance, color transparency, and performance, whether the geometric structure, slope, and inserts of plastic parts are reasonable, the allowable degree of welding lines, shrinkage holes and other forming defects, whether there is coating Assembly, electroplating, silk screen printing, drilling and other post-processing.

Estimate whether the molding tolerance is lower than the tolerance of the plastic part, and whether the plastic part that meets the requirements can be formed. In addition, it is necessary to understand the plasticization and molding process parameters of plastics.

2. Process information

Understand the requirements of glue feeding method, beer machine model, plastic material performance, mold structure type, etc.

The molding material should meet the strength requirements of plastic parts, and have good fluidity, uniformity, isotropy, and thermal stability. According to the purpose of the plastic part and whether it is post-processed, the molding material should meet the requirements of dyeing, metallization conditions, decorative properties, necessary elasticity and plasticity, transparency or reflection properties, adhesiveness (such as ultrasonic) or weldability.

3. Select molding equipment

Injection capacity, clamping pressure, injection pressure, mold installation size, ejector device and size, nozzle hole diameter and nozzle spherical radius, sprue sleeve positioning ring size, mold maximum and minimum thickness, template stroke, etc.

4. The specific structure of the mold

Two-plate mold, three-plate mold. Whether the mold structure is reliable, whether it meets the process technology of plastic parts (such as geometric shape, surface finish and dimensional accuracy, etc.) and production economic requirements (low cost of parts, high production efficiency, mold can work continuously, long service life, labor saving Wait).
