Building on over 30 years of experience, we are constantly refining our methods to guarantee first-class technology that saves energy, time and raw materials. This technology enhances the barrier properties of the preforms and reduces maintenance costs as well as downtimes. The co-injection technique, a Hofstetter development, allows all the advantages of multi-layer moulding to be combined for maximum effect. Moulds for Plastic Packaging. Our thin-wall technology offers major advantages in the production of packaging articles – be it for foodstuffs, catering or hygiene products, paints, oils or delicate and light-sensitive products. We are the first to bring barrier injection moulding to maturity in the plastic packaging trade. Injection moulds for cartridges, tubes and other containers are also a speciality of our designers. We manufacture moulds for standard cartridges with 2 to 16 cavities. The cosmetics industry uses tubes made in Hofstetter moulds for lotions, creams and toothpastes. The choice of cavities from 2 to 16 guarantees economical production, while the revolutionary two-chamber system opens up a range of new applications. After-sales.
