Injection compression moulding is used for producing optical items as well for the manufacture of thermoset, ceramic and metal powder, LSR and thermoplastic moulded parts. Reasons for its use include:

		Reduced cycle times
		Suppression of open jet formation
		Prevention of sink marks
		Reduced flow path/wall thickness ratio
		Reduced component tension
		Improvement in specific evenness
		Enhanced moulding accuracy and part quality
		Increased component strength

 
The principle involved is as follows. The plastic is injected into the partially open, unpressurised mould. The mould is only fully closed once the injection process is completed by the ALLROUNDER. The even clamping pressure generated in this manner forms the final moulded part.
 
By using injection compression moulding on our ALLROUNDERs, you primarily benefit from precise compression paths and a freely-configurable compression sequence, precisely tailored to your product.
 
Our offerings are characterised by:

		Free, individual programmability of the compression sequence via SELOGICA
		Simultaneous machine movements, also on hydraulic ALLROUNDERs
		Fully-hydraulic ALLROUNDER clamping units with long compression paths and long compression phases
		Precise mould positioning with high repeat accuracy thanks to servo-electric, toggle-type clamping units
		Utilisation of the advantages of main axis compression
