OverviewThe dual-compound injection press produces parts that integrate two (or more) compounds with different properties to combine technical performance and cost optimization. By injecting multiple compounds in one process, assembly steps are eliminated and the use of higher-cost compound is limited to functional areas only.
Injection configurations- Injection from the top
- Injection from the bottom
- Injection from the side
- Injection from the back
Objectives / Benefits- Produce multi-material parts with distinct compound properties
- Eliminate assembly operations and reduce cycle complexity
- Integrate low-cost compound while confining premium compound to functional zones
Production methods for dual-compound parts- Two sequential injections into two complementary cavities
- Simultaneous injection into two different cavities or two separate part cavities
- Simultaneous (or offset) injection into a single cavity
Injection path optionsInjection can be performed directly into the mold or via a dedicated cold runner block (CRB) that integrates multiple compound circuits for controlled feed and reduced downtime.
Dual-compound CMX (multistation) descriptionThe CMX multistation dual-compound press features 4 rotating stations and 2 injection units. It enables synchronous injection, curing and demolding of two compounds in the same mold station, delivering high hourly throughput and operational flexibility.
Productivity- Significantly higher hourly production: reported productivity gains of +50% to +100% versus a single-station 400 t press
- Fast mold changeover: example ~10 minutes for the 4 molds on multistation machines
Flexibility- Ability to disable a mold or station when required
- Programmable different shot sizes per unit or station
Versatility- Stripping station adaptable to multiple kinematics
- Machine can operate simultaneous injection, sequential injection, or use only one injection unit if necessary
