ENGEL - Rubber moulding machine for customer trials

ENGEL, a world leader in the design and manufacture of injection molding machines and part-handling automation systems, has equipped their Technical Center in York, PA with an ENGEL elast 1500/285 VC US rubber injection molding machine, capable of processing either strip feed rubber material or solid silicone, for use in customer mold trials and customer training.  The ENGEL elast 1500/285 VC US is a horizontal tiebarless machine, with all the features and benefits of this tried-and-tested design concept,  including minimum retooling times (even for bulky molds), unrestricted use of the platen surface, and platen parallelism for exacting precision requirements. The machine’s 1500cc FIFO (first-in-first-out) injection unit utilizes a 6 liter hydraulic stuffing device for solid silicone material feeding. The injection unit is also equipped with an automatic strip feeder with strip break detection for feeding rubber strips. With ENGEL’s short design injection nozzle there is very little pressure loss during the injection process. This allows the molder to have the maximum available injection pressure when required. The 285 ton clamping unit is equipped with 550mm x 650mm heating platens on both the fixed and moving machine platens, with 12 auxiliary heating zones for mold heating.  These multi-zone heating platens, with self-adjusting temperature controls, guarantee extremely reliable processing and high quality molded parts The machine’s hydraulically operated side ejectors, located on the fixed and moving platens, allow the shuttling of multiple plates for complex parting lines and easier part demolding. Additionally, the machine has an extremely rigid brushing device, using a double beam brush system equipped with two brush modules for brushing parting lines or part demolding. The system is set up with 2 pressurized Piovan water temperature control units which are capable of maximum temperatures of 140 degrees C. These temperature control units are fully integrated into the machine heating control, providing consistent temperature control of the injection chamber and cold runner system.  The ENGEL elast 285 utilizes the standard Engel CC200 controller, which provides superior flexibility of process set-up and machine sequencing, with 4 freely programmable DI/O for increased molding flexibility. The CC 200 controller uses a touch screen for input, with the option of either functional graphs or keyboard pop ups, and offers free programming of cycle sequence via graphical icons.

In New Zealand, ENGEL is represented by TECHSPAN GROUP, since 1979.
