Hasco: Mould-making productivity for 50 years

In 1960, Rolf Hasenclever submitted a patent to facilitate the production of injection moulding tools by using standardised elements. This meant considerably faster manufacture times of injection-mould tools, as well as being more economical and reliable in service.Mould construction
The proven pre-hardened, high-quality steel Toolox33 is now additionally available as an undrilled P-plate, as a finished cavity plate in K20 quality or as K252 with finish machining allowances in the system drillings. The special stability features of this material allow finish-machining in one setting. Using the Hasco clamping fixture A8001 likewise reduces set-up times. The homogeneous, sulphur-free structure permits high gloss polishes and acid etch graining. The choice of material has a major influence on the economic efficiency of mould construction and the service life of the tool.Demoulding
The comprehensive product range with latch locking units, two-stage ejectors, transmission elements and collapsible cores for demoulding internal threads and undercuts offer the user customised application possibilities. The new ejector set cover Z1216/... protects the ejector set against penetration of dust and foreign particles thus reducing downtimes during production.Temperature control
A wide range of cooling elements dissipates the heat from the cavity at every desired position and thus ensures optimum cycle times. The product line starts with the entire range of hoses and connections, through spiral cores and diverting elements. The new diverting plug Z9675/... is used to position the ejector bore through the cooling channels, allowing significantly greater flexibility in tool design. The new intermediate size M9x1 for the sealing plugs Z94/... and Z940/.... can now seal size 8 cooling channels with considerably less effort.Hot runner technology
In the hot runner segment, the company will highlight various needle valve solutions as well as innovative solutions for difficult gating positions in manifold tools. Two new control units have also been added to the range. With the Multi hot runner control unit Z1240/..., Hasco is offering a unit of the highest class in terms of efficiency, convenience and reliability.
