PREFORMS ON TOP FORM.

The continuous improvement of our technology and the standards we impose for precision, durability and flexibility pay a number dividends in the production of preforms. Our PET moulds achieve top marks in several respects: energy, material and cost efficiency; short cycle times; optimised start-up processes and good preform behaviour during stretch-blowing. Our moulds are always produced to meet the needs of the customers as closely as possible.

EXEMPLARY APPEARANCE.

Mould follows function or, as we put it more precisely, preform follows mould. We’ve been developing moulds for PET preforms for nearly 40 years. In all this time we’ve continuously expanded and perfected our concept, our technology and our know-how in the area of mould design. We’re as experienced in the design of preforms as we are in the manufacture of fully mature injection moulds.

TOP-LEVEL PERFORMANCE.

Minimum wall-section differences.
Up to 50% reduction in cooling water consumption.
More than 10 million production cycles can be achieved before an overhaul.
High surface and wear protection thanks to OH Xtreme®.
Minimum maintenance with maximum convenience.
Backwards-compatible and can be converted.

INTUITIVE PRODUCTION.

People are the focus in everything we do – from development to planning to correctly packing the mould ready for dispatch. Our employees can rely on the latest production technologies and high-precision machine tools. All of our wear-resistant mould parts and durable extra components are made from high-grade tooling steel. Otto Hofstetter quality also means that all products are finished by hand. A first-class mould doesn’t just happen by accident.

NEW: TOP PERFORMANCE ROTATED 90 DEGREES.

For decades they have set benchmarks for performance and durability: our injection moulds for PET preform production. Well-known manufacturers all over the world benefit from getting more than ten million cycles without revision and a service life of over 20 years. Now, our legendary technology is also available for moulds in side-entry systems.

SIDE-ENTRY MOULDS WITH TOP FLEXIBILITY.

Our broad portfolio of moulds and post-cooling units cover a wide range of PET preform production. What isn’t standard, we build according to your wishes.

OVER FORTY YEARS OF EXPERIENCE BUILT-IN.

Otto Hofstetter AG designed its first injection mould for PET preforms in 1977. The client back then, the Continental Can Company, had to produce new beverage packaging for Coke and Pepsi. Since then, this Swiss family-owned company has regularly pushed the boundaries of technical possibilities and made the production of PET preforms cheaper, more efficient and more convenient.
