Jaroschek Displacement Process Benefits

The JDP provides features that benefit both the Moulder and the OEM Customer:

JDP Features and Benefits for the Moulder
Features	Benefits
By displacing plastic	Reducing material weight by up to 50% Reducing time cycles by up to 40%

By completely filling the mould cavity in one movement	Avoidance of any hesitation marks

By control of plastic injected into a preselected volume of the mould cavity and side cavities	Repeatability of: - machining shot and moulding wieghts - thicknesses of hollow sections

By using gas to transmit pressures throughout the moulding	Uniform pressure throughout moulding when cooling Lower in-mould pressures with reduced press lock forces

By using JDP Version 3 - displacing material back into the machine cylinder	No need to recycle displaced plastic

JDP Features and Benefits for the OEM Customer
Features	Benefits
By reducing weights and time cycles	Reduced production costs and therefore prices

By moulding more uniform thicknesses and applying gas pressure to thicker sections	Improved quality of moulding surfaces including elimination of sink marks

By avoiding high hold on pressures and avoiding plastic flow during cooling	Reduced moulded-in-stress and therefore tendency to distort after moulding
