Injection mold construction is the process of creating molds that are used to perform injection molding operations using an injection molding machine. These are generally used to produce plastic parts using a core and a cavity. Molds are designed as two-plate or three-plate molds, depending on the type of component to be manufactured.
A parts book, parts catalogue or illustrated part catalogue is a book published by a manufacturer which contains the illustrations, part numbers and other relevant data for their products or parts thereof.
Filter for nozzle with a plastic toy next to it. Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts and components, toys, pocket combs, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products available today.
Single-piece cores do not need to be assembled because they are made in a split core box. A split core box, like it sounds, is made of two halves and has at least one hole for sand to be introduced. For simple cores that have constant cross-sections they can be created on special core-producing extruders. The extrusions are then cut to the ...

This newest form of molded pulp is the highest quality of thin-walled products available today. The process uses "cure-in-the-mold" technology which produces well defined, smooth-surfaced molded pulp products. After being formed, the product is captured in heated forming molds that presses and densifies the molded products.
Setup and production of shell mold patterns takes weeks, after which an output of 5–50 pieces/hr-mold is attainable. [7] Common materials include cast iron , aluminum and copper alloys. [ 1 ] Aluminum and magnesium products average about 13.5 kg (30 lb) as a normal limit, but it is possible to cast items in the 45–90 kg (100–200 lb) range.
The Caldwell catalogue is an astronomical catalogue of 109 star clusters, nebulae, and galaxies for observation by amateur astronomers.The list was compiled by Patrick Moore as a complement to the Messier catalogue.
