Injection molding press models are best known for their terrific speed, accuracy, and repeatable method for rubber goods production. They are great for large production volumes and have complex processing methods, typically producing excess scrap. We offer three different injection molding models by TMP Asian.


Injection molding press models offer many molding and process options that can help optimize cycle time and solve production problems. These options cover specialized cycles such as injection/transfer, injection/compression, preform, vacuum purge and volumetric bump cycles. Injection molding press models are ideal for large production volumes that require close dimensional tolerances, such as grommets, O-rings, and seals. They are great for delicate, small- to medium-sized parts, insert molding, and low- to medium-high durometer materials.

However, injection molding requires much more processing knowledge and strict control over the machinery and material parameters. One major issue with injection molding of thermosetting materials is that, under heat, many materials will first soften, and then harden to an infusible state. So, take great care to limit to the amount of time and heat put into the thermoset material. Otherwise, problems may occur, such as minor material degradation, part non-uniformity, or complete freezing up the injection unit. Also, the equipment is generally not suited for short production runs because tooling and material changeover can be very timely and costly.

Our customers enjoy shorter production cycles with our TMP Asian injection molding press models, which means a lower unit cost. Plus, they can maintain close dimensional tolerances for precise production requirements. The specialized cycle availability provides solutions to tricky production problems. And, customers can obtain lower production cost with large production volumes.

However, the injection molding press, tooling and auxiliary equipment can add up to higher investment costs. The processing method is complex and typically produces a high excess of scrap material. They do not work well with filled materials and generate the greatest amount of material degradation. Injection molding presses also require a long set-up time, closed loop processing feedback, tooling maintenance due to erosion of gates or runners, and a higher skill set for operators and processing staff because of the specialized process and cycle parameters. Plus, they cannot process high durometer materials because of their low cavity pressure.
