Dolosse moulds are in the foreground - Durban, South Africa. Dolosse are normally made from un-reinforced concrete, poured into a steel mould. [1]: 11 The concrete will sometimes be mixed with small steel fibers to strengthen it in the absence of reinforcement. Durban's South Pier with a line of interlocking dolosse, South Africa
Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is ...
Compression molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, while heat and pressure are maintained until the molding material has cured; this process is known as compression molding ...
In its uncured state, silicone rubber is a highly adhesive gel or liquid. To convert it to a solid, it must be cured, vulcanized, or catalyzed.This is normally carried out in a two-stage process at the point of manufacture into the desired shape, and then in a prolonged post-cure process.
A matching form will be placed on the opposite side to create the space to pour concrete into. Formwork is molds into which concrete or similar materials are either precast or cast-in-place. In the context of concrete construction, the falsework supports the shuttering molds. In specialty applications formwork may be permanently incorporated ...
