compression mould for glass tiles
The parison (1) is transferred to the compression mould (2) in such a way that it falls freely from the preform mould into the compression mould (2).
The aim of the invention is to produce a compression mould having a comparatively long shelf life on the one hand and whereby the tendency of the pressed material to adhere to the compression mould after being pressed is reduced on the other hand.
The use of AlN sintered ceramic as a material for a compression mould for manufacturing optical parts made of glass or glass ceramic permits polished moulded optical parts of high surface quality and high precision to be obtained.
The moulding tool (3) is thereby closed, molten polymeric material supplied and the mould cavity (4) filled therewith.
Fixation of the unit or object (1) in an open moulding tool (3) is obtained when the tenon (5) or groove (5') of said unit or object (1) is brought into engagement with the groove (10) or tenon (10') of said mould cavity (4).
The invention also relates to mold tooling (5) for carrying out the process.
The invention relates to a pressing tool for producing molded parts or similar, which is configured such that said pressing tool can oscillate at least temporarily during the pressing process by means of vibrations or other influences.
The device and method of the invention utilizes the opening-closing operation of an injecting mould or a pressing mould and completes the steps of withdrawing core, unloading mould and inserting core, synchronously.
A system (10) is provided for unloading finished parts from and also loading new raw material (68) into a compression mold having two mold halves (62, 64) in which the mold halves are in a spaced apart position.
The invention relates to a pressing tool for producing molded parts or similar, which is configured such that said pressing tool can oscillate at least temporarily during the pressing process by means of vibrations or other influences.
The aluminum chips (a) freed of the paint and pigment are fed into a compression molding machine (40) and again molded into an aluminum molding (b).
