A veritable surge in development for moldmaking
From Standard Part to Engineering Solution
Half a century ago, on February 13, 1960, the mold maker Rolf Hasenclever in Lüdenscheid, Germany, applied for a patent, which represented a veritable surge in development for moldmaking. The patent describes the details of the concept, the shapes, and tools used for metalworking and plastics processing that are built from a modular system of industrially manufactured, exchangeable standard components. At that time, every mold was a unique item, manufactured from a solid block of raw steel. Hasenclever, founder of the Hasco company that is named after him, was involved in designing the essential functional modules from which standard components for injection machine molds are developed.
The standardization of constructional elements paved the way for the high precision of standard parts – which is taken for granted today – and the simple exchangeability of wear-prone components that previously had to be copied and manufactured individually at great expense. The concept became established, and to an increasing extent platens were no longer produced individually, but purchased as standard parts. Thanks to the reduced lead times, moldmakers were able to concentrate their efforts and machining time on the actual process of creating values, i.e. implementing new ideas for plastic products.
The product range is being extended continuously in order to increase productivity in moldmaking. Originally consisting mainly of platens, ejectors, and guiding elements, today’s product range includes de-molding mechanisms such as latch locking devices, two-stage ejectors, prefabricated slide systems, a complete range of couplings for installing a cooling system, and quality steels such as Toolox33, Toolox44 or 1.2099 Hasco.M, which offer significant machining advantages for the moldmaker. The importance of CAD was also recognized at an early stage, and since then, the Hasco Standard Module greatly simplifies design work with all conventional CAD systems.
The hot runner technology is providing ever more demanding solutions for engineering plastics, tight mounting spaces, and multi-cavity molds. Hereby, the trend is away from self-made solutions using standard components towards individually designed systems up to entire hot sides, including needle shut-off solutions and precisely matched control technology.
50 years after their invention, standard parts are no longer just components – they have become ready-made engineering solutions jointly developed by the manufacturer and the customer with the aim of turning new ideas into high-quality products. Every product is subjected to strict quality checks in order to ensure precision, safety, and exchangeability. The standard solution also provides a comprehensive logistics network that ensures just-in-time delivery worldwide.
