Injection Molding Presses make dual, independent injections.
Press Release Summary:
Presses make sequential or simultaneous injection of 2 materials, such as rubber, liquid silicone, or thermoplastic elastomers. Machines work 3 ways: 2 consecutive shots into adjacent cavities; simultaneous or sequential shots into single cavity; or simultaneous shots into 2 separate cavities. Onboard PC controls operation of dual injection heads, closing/clamp unit, and all other electrical, hydraulic, and mechanical machine functions.

REP Offers Dual-Injection Molding Presses
REP, long-time leader in injection presses for rubber, liquid silicone, thermoplastic elastomers and other compounds, offers dual-injection machines for molders requiring sequential or simultaneous injection of two materials.
Molders of electrical, automotive, appliance and aerospace parts will benefit from REP dual-injection machines, as they can run these high-production presses efficiently and for greater per-part profitability. Conductive and semi-conductive insulator materials, even a rubber and TPE compound, can be co-molded in a single operation, owing to the dual and independent injection units onboard these presses. Secondary assembly can be virtually eliminated and, in many parts, a lower-cost, material can be used in a non-dynamic section of the part. Bi-compound hoses, engine mounts and various electrical insulators are examples where REP dual-injection machines can achieve superior part integrity, as well as lower overall cost to manufacture.
On the REP dual-injection machines, molding can be done in three ways: two consecutive shots into adjacent cavities; simultaneous or sequential shots into a single cavity; simultaneous shots into two separate cavities. Injection may be direct or through the patented REP cold runner block, which saves expensive raw material by eliminating waste.
REP supplies these presses with its proprietary G8 controls, which comprise an onboard PC to fully integrate and maintain operation of the dual injection heads, the closing/clamp unit and all other electrical, hydraulic and mechanical machine functions. Separate easy-to-read displays are provided on a single control panel for operator convenience.
Total material flow flexibility has been designed into these REP presses, which are offered with standard 2 x 25 oz. shot capacity and 175-ton clamp force, plus 430mm x 510 mm ( 16.93" x 20.08") platens.
Custom units are available to meet molder requirements. Case histories on request.
