Choosing A Rubber Molding Machine - What to Look For!

As a manufacturer of rubber molding machines, Twin Pines recognizes that many factors go into choosing what type of machine is right for your operation. With this in mind, we have developed a list of the most important criteria to consider when purchasing a rubber or plastic molding machine.

Rubber Molding Safety:

As the old adage goes, “safety first.” Many molding machines use a hydraulic safety, which means that when the hydraulics fail, the machine slams shut. Twin Pines offers a spring loaded, mechanical safety lock option for its machines. This prevents the clamp from moving up and down unless both palm buttons are engaged, ensuring the operator’s safety regardless of the condition of the hydraulics.

Ease of Use:

When choosing a machine you always want to make sure that its interface is not cluttered or overly sophisticated. This can lead to mistakes or frustration, and requires longer periods of training for operators. That's why Twin Pines makes sure that all of its rubber and plastic molding machines are simple and intuitive to use. Our molding machines can be completely controlled from one touch screen.

Platen system:

Over time, the platens on rubber and plastic molding machines will slowly but surely shift until they are no longer parallel. This results in a much greater frequency of flashing. To eliminate this problem, Twin Pines developed a platen leveling system for its molding machines. Even after the platens have shifted, the leveling system guarantees that they will always be parallel during operation.

Nozzles:

The difference between a fixed and moving nozzle is critical when choosing a rubber or plastic molding machine. Fixed nozzles can cause sheering which forces the operator to spend time disassembling the machine in order to fix the problem. The adjustable nozzle offered by Twin Pines eliminates this waste of time by prevent such a problem from ever occurring.

Shot Size Repeatability:

Arguably, one of the most important factors, a consistent shot size is crucial to all rubber and plastic molding operations. Inconsistencies associated with cheaper machines can create a litany of problems for manufacturers. Not only does Twin Pines build its machines to the highest standards, but we also test them to make sure they meet the level of quality we demand. A 300 shot analysis showed a variation of no more than +/- .2 grams.
