Plastic Fabrication

ReManTech suppliers offer traditional thermoforming, RIM, and injection molding. We can help you decide on which process is best for your product application. Below we have outlined some information about the Plastic Fabrication processes available.

Vacuum & Pressure Thermoforming 

Two methods of plastic thermoforming exist: vacuum forming and pressure forming. Both evacuate air from the sealed space between a heated plastic sheet and a mold to make the sheet conform to the mold. Pressure forming is for parts requiring higher precision and features such as sharp undercuts; to achieve these features, compressed air is added to the operation, from 20 to as much as 150 psi.

For fast set-up and production of plastic parts, (especially larger parts), vacuum thermoforming or pressure & vacuum thermoforming with sheet plastics can be a lower cost process and method of choice.

Reaction Injection Molding – (RIM)

The difference between reaction injection molding (RIM) vs. injection molding is the method by which the material being molded is solidified. Injection molding is a process where a thermoplastic polymer is heated to its melt temperature and injected into a mold at high pressure and rapid flow rate.

Reaction injection molding (RIM) is similar to injection molding except thermosetting polymers are used, which requires a curing reaction to occur within the mold. Common items made via RIM include automotive bumpers, air spoilers, and fenders.

RIM advantages are: larger parts, soft or hard, allows more detail, thinner walls with less sink, paintable, etc...

Injection Molding

ReManTech represents a very high quality offshore injection molder. They are ISO 9001 & 14002, TS 16949 for automotive, and ISO 13485 for Medical. Our offshore supplier began 30 years ago designing and Mfg. tooling. They have since evolved into providing end products as well for a long list of major OEM's. They are an ultra high quality supplier even by US standards. They do not cut corners on tooling design and only use the best tool steel. In-house tooling design and manufacturing provides for shorter lead times/time to market. Offshore tooling costs can be 40% to 60% less than domestic tooling costs.
