Troubleshooting Guide for Injection Molding II

Troubleshooting Guide for Injection Molding II Moisture Streaks Physical cause During storage or processing, moisture is absorbed by the granules, forming water vapour in the melt. Due to the velocity profile at the flow front, gas blisters are pushed to the surface of the melt as shown in Figure. Since they want to compensate the

Troubleshooting Guide for Injection Molding I

Troubleshooting Guide for Injection Molding I In most cases, the surface quality of thermoplastic injection moulded parts is the main criterion for their quality. Due to the complex interrelationship between the moulded part and the mould, the moulding compound and the processing, it is often very hard to recognise the origin of problems and thus

Basics of Injection Molding Design

A detailed review of the plastic part design should be conducted prior to the design and manufacture of the injection mold. The design review should consider the fundamentals of plastic part design, as well as other concerns related specifi cally to mold design. Some of the most basic part design considerations are next discussed. Uniform

The Basic Concepts of Plastic Injection Molds

Injection molding is a process by which plastic pellets are melted using heat and shear in an extruder and injected, at high pressure and flow, into an injection mold to form the part. It is one of the most productive and cost-effective means of producing a high-quality product. While this process seems straightforward, it is

An Introduction to Plastic Injection Molding

The designer should always decide whether using injection molding is the best approach to mold the item before moving further with it. Have other approaches or product designs that employ different production techniques and utilize the same, comparable, or different materials—or materials that would allow for a similar final result, or even one of higher

General Tolerance – ISO 2768

Part 1 ISO 2768-1 is intended to simplify drawing indications and specifies general tolerances in 4 tolerance classes (f – fine, m – medium, c – coarse, v – very coarse). It applies for the linear dimensions and angular dimensions such as external sizes, internal sizes, step sizes, diameters, radii, distances, external radii, and chamfer
