Sprueless and Runnerless Moulds

Sprueless and Runner-less Moulds The feed system which is necessary for material conveying is, on many jobs, the thickest part of the moulding shot. This means that the rate of setting or hardening of the material is dictated by the…

How to process the plastic material correctly

The successful application of plastics materials depends on the correct choice of material, and the optimization of its properties to ensure a satisfactory service life,at a price which is competitive. The designer must have a thorough knowledge of materials and…

Cutting Tools in Die and Mold Industry

In die and mold manufacturing, there are different machining operations: cutting (milling, drilling, reaming, etc.), abrasive machining (grinding, polishing, honing, etc.) and EDM. Even water jet cutting is used by die and mold makers. However, metal cutting remains to be…

Vertical Injection Molding Process

Vertical Injection Molding Process What distinguishes a micro injection process from a “normal” Vertical Injection Molding process? Except for parts or structure sizes, the process is almost identical. Oen, even the same procedures are applied, both in the actual injection molding…

plastics

  The term “plastics” has been applied to those synthetic non-metallic materials that can be made sufficiently fluid to be shaped readily by casting, molding, or extruding, and which may be hardened subsequently to preserve the desired shape. Plastics as…

draft and hole design

Unless otherwise specified ,a slight draft is ordinarily given to the vertical surfaces of the piece. The reason for this is obvious when consideration is given to the fact that the injection molding plastic piece has to be released with the…
