The Injection moulds for technical parts<\/strong> meeting the most complex requirements: under-cut geometries, tight tolerances, integration of mechanical functions (clips, hinges, threads), critical appearance areas, or high mechanical stresses. They incorporate advanced features such as tiroirs, noyaux mobiles, \u00e9jecteurs sp\u00e9cifiques, conformal cooling<\/strong> and differentiated thermal systems.<\/p>\r\n\r\n\r\n\r\n At Hybster, we design and supply technical moulds for demanding sectors: electronics, automotive, mobility, lighting, medical, EV charging. Our integrated approach guarantees an optimal balance between complexity, reliability and unit production cost<\/strong>.<\/p>\r\n\r\n\r\n\r\n A mould for a technical part is distinguished from a standard mould by its ability to reproduce geometries that cannot be demoulded with a simple two-plate mould. Typical features:<\/p>\r\n\r\n\r\n\r\n To understand the manufacturing constraints for technical plastic injection moulded parts, consult our dedicated article: Plastic injection of technical parts<\/a>. For parts combining rigid and flexible elements, see our two-component moulds (2K injection)<\/a>.<\/p>\r\n\r\n\r\n\r\n The side and moving cores allow for external or internal undercuts to be created: side openings, external threads, dovetail forms. Activated mechanically (cams) or hydraulically, they retract before ejection to release the part.<\/p>\r\n\r\n\r\n\r\n Le conformal cooling consiste \u00e0 int\u00e9grer des canaux de refroidissement qui suivent la g\u00e9om\u00e9trie de l’empreinte, fabriqu\u00e9s par Direct Metal Laser Sintering (DMLS)<\/strong>. Benefits: reduced cycle time (20\u201340%), improved part flatness, reduced internal stresses. Applicable to critical mould cavities only (hot spots or areas that are difficult to cool).<\/p>\r\n\r\n\r\n\r\n The mould incorporates a precise positioning device for metal inserts (brass threads, pins, contacts, captive nuts). The insert is placed manually or by robot before injection, and then the polymer is moulded around it to create an inseparable assembly.<\/p>\r\n\r\n\r\n\r\n For large parts (bonnets, dashboards), several injection points are opened\/closed at precise moments to control the flow and eliminate weld lines. Requires a system with hot runner with shut-off nozzles<\/a>.<\/p>\r\n\r\n\r\n\r\n Detailed analysis of your technical part: mouldability feasibility, functional ergonomics, rheological simulation to anticipate weld lines and warpage. This is the most critical step for the successful creation of a technical mould.<\/p>\r\n\r\n\r\n\r\n Int\u00e9gration des dispositifs m\u00e9caniques (tiroirs, noyaux, \u00e9jection), du syst\u00e8me thermique (conformal cooling \u00e9ventuel), et de l’alimentation (canaux chauds si grande s\u00e9rie). Choix des aciers selon les contraintes (1.2767, 1.2316, H13).<\/p>\r\n\r\n\r\n\r\n Technical moulds require experienced mould makers for complex movements. Hybster selects its partners according to complexity (France, Eastern Europe, or China for certain projects) with systematic technical monitoring.<\/p>\r\n\r\n\r\n\r\n Technical moulds require a longer setting-up period (2-5 days in the press) to optimise all parameters: cavity balancing, movement synchronisation, part finishing. Hybster oversees this critical phase.<\/p>\r\n\r\n\r\n\r\n <\/p>\r\n\r\n\r\n <\/p>","protected":false},"excerpt":{"rendered":" Moules d’injection pour pi\u00e8ces techniques \u00e0 forte valeur ajout\u00e9e.
