Compression molds automatic

Automatic molding — A PTFE molding technique for small parts in automatic presses, which is faster than standard compression molding. [Pg.168]

Typical Applications. Common compression-molded thermoset products include electrical equipment, appliance handles and knobs, dinnerware, distributor caps, under-the-hood parts in general, automatic transmissions, brakes, and pumps. [Pg.683]

A higher pressure than ordinary compression molding is required for automatic molding because... [Pg.167]

Isostatic molding is a suitable alternative to compression and automatic molding techniques for the production of PTFE parts with complex shapes in a wide range of sizes. Compression molding can supply a stock shape which can be machined to obtain the desired shape. The drawback to this option is the... [Pg.168]

Compression molds can be divided into hand molds, semiautomatic molds, and automatic molds. The design of any of these molds must allow venting to provide for escape of steam, gas, or air produced during the operation. After the initial application of pressure the usual practice is to open the mold slightly to release the gases. This procedure is known as breathing. [Pg.158]

Automatic press n. Hydraulic press for compression molding or an injection machine which operates continuously, being controlled mechanically, electrically, hydraulically, or by a combination of any of these methods. [Pg.76]

Compression molding presses are generally classified according to method of operation (i.e., hand, manual, semiautomatic, and fully automatic). They may be classified also according to their source of power (i.e., mechanical, hydraulic, and... [Pg.105]

SPMC materials are developed specifically for use in automatic molding systems such as injection, transfer, and compression molding. SPMC is available in various colors, flow grades, and shrinkage factors. [Pg.515]
