Capabilities


Injection Molding Machines
We offer a selection of hydraulic, electric and hydraulic/electric machines. The project is optimized for tooling and choice of equipment based on the needs of the individual project. Their equipment ranges in size from 15 tons to 450 tons in size. Alternatively, we have machines offering vertical and horizontal injection along with vertical and horizontal clamping which offers you ideal combinations of gate location and clamp orientation for insert molding operations.
Secondary Equipment and Facilities

 

Quality Tools and Equipment

 

Tool Room Equipment
Each fully equipped tool room has the ability to manufacture complete and finished tooling along with handling normal tool maintenance and repair. In many cases new tooling is produced in Asia using established tooling companies with longstanding relationships. This method of tool production usually results in a cost savings with the quality of the tooling being analogous to domestic tooling. With the alternate molding facility, all tools are manufactured in house and, as long as the project remains at the location, the tools are guaranteed for life including normal maintenance and full replacement if necessary.
