MC-MJ Series
Sandwich Moulding
Standard Sandwich Mould
Foamed Core
By using a standard material for skin layer and a foamed material for the core layer, it is possible to reduce the product’s weight. Sink marks of thick-wall products are prevented and the surface has a soft touch and the foam provides sound absorption.
Gas Barrier
An inner core with gas barrier properties prevents the permeation of gases entering the product. This can be used in food packaging to improve the shelf life of the contents inside.
Stronger High Finish Products
The core material can include fillers such as glass fibre or minerals to increase a product’s strength. Together with a standard material skin to give a high-quality exterior finish.
Marble Moulding
Marble moulding is the injection of two different material sequentially to create a marbled pattern effect. This can be used as a cosmetically to enhance a product appearance.

Glued Fabric insert
Moulding sequence
- Mould closes to controlled open position
- Injection starts
- Mould compression
- Mould open and ejection
Meiki Pre-Press System (MPPS)
The Meiki Pre-Press System preloads the material in the screw and barrel using a shut-off valve at the nozzle tip. The screw moves forward closing the check valve on the head, trapping the material inside the barrel at a constant pre-injection pressure achieving an even load density. The screw position after pressurisation is taken as the injection shot volume starting point by the MPPS control system. This enables a constant shot volume to be injected into the mould. Removing any unwanted variation in final product quality.
