Grupo Perplast runs all-electric JSW and Sumitomo Demag machines. Compared with hydraulic machines they offer:
- Higher precision and part-to-part repeatability, ideal for caps and precision parts.
- Lower energy use and quieter operation.
- A cleaner process, with no hydraulic oil near the product.

Besides the 23 in the table, the plant has a BOY 15 S for very small parts. Full specs (screw, pressure, mold height and platens) are available on request.
Clamping force (tons)
The force that keeps the mold closed while plastic is injected. Large parts and high-cavitation molds need more tons.
Shot capacity (grams)
The maximum amount of plastic the machine injects per cycle, split across all mold cavities. Example: a 4-cavity mold with 50 g parts needs a shot of about 200 g, plus the runner.
Part weight (0.2 g to 1,000 g)
The weight of each finished part. Grupo Perplast makes parts from 0.2 g up to 1 kg; small parts use multi-cavity molds to produce more per cycle.
Tie-bar spacing
The clear space between the machine's tie bars. It sets the maximum mold width that fits.
QUALITY ASSURANCE
Every detail measured, down to 10 microns
Grupo Perplast uses Keyence measuring equipment to verify dimensions and surface details with exceptional accuracy throughout production, guaranteeing precision and consistency in every part.

SURLYN® SPECIALISTS
The gloss and clarity of glass, in a plastic cap
Grupo Perplast processes over 150 tons of Surlyn® a year with scrap below 3%. In 2014 it showed its first Surlyn® injection mold at Plastimagen, and in 2019 it brought Surlyn® to spirits for the first time, together with Dow.
