Die Umsetzung des Bauteils erfolgt im Montagespritzguss. Damit wurde eine komplette Spritzgussprozesslösung ohne zusätzlichen Montageprozess für die Lagerstellen realisiert. Zunächst werden die Lagerböcke aus PPA gespritzt und im Umsetzverfahren innerhalb des Spritzgusswerkzeugs zur Anspritzung des Grundkörpers aus PPS mittels Handling-Hand automatisiert umgelegt. Somit werden werkzeugfallend zueinander bewegliche Teile in einem Fertigungsverfahren hergestellt.

Mould

Mold making as a guarantee of success The key to the economical production of high-quality plastic parts lies in a perfect injection molding tool. With over 20 years of experience, we stand for a variety of ideas and an outstanding reputation for special quality awareness. We have special know-how in insert/outsert technology and we manufacture high-end molds for the reel-to-reel process. All parts are manufactured entirely in-house in Germany. Our high standard is based on our experience from our own production. Our quality management ensures maximum efficiency. We develop our products in close cooperation with the customer and the requirements from practice. In this way, we lay the foundation for outstanding end products and smooth production right from the design stage. Our customers value our practical experience and an uncomplicated and flexible way of working.

The Starting Point – Conventional mould for plastic injection moulding The existing mould, made of mould inserts, plates, clamping plates, and standard parts, measures 125 x 125 x 130 mm and weighs about 60 kg. The project aimed to optimize the injection moulding process by reducing cycle time and simplifying the assembly complexity. Using additive manufacturing, the mould was redesigned and its topology optimized according to loads and requirements. The result: a smaller, lighter mould with integrated conformal cooling. The Challenge – Maintaining functionality During topology optimization, critical functional surfaces like mold half alignment, ejector system position, and machine interface had to be preserved. The design also accounted for subsequent clamping for CNC post-processing. Distortion during metal 3D printing posed another challenge. Optimal part orientation, support design, and process simulations helped detect distortion early and avoid scrap. The “first time right” principle is key here. The Approach – End-to-end process with Siemens NX From redesign, material selection, and cooling integration to FEM and cooling simulations, data prep, print simulation, metal 3D printing, finishing, and CNC machining, the process was digitally mapped and efficiently executed. Quality control was optical and tactile. The mould was then successfully deployed in production. The Result – A step toward the future of mould making The new 3D-printed mould features smaller dimensions and nearly 50% less mass. Reduced weight simplifies installation and lowers machine clamping forces. Thanks to conformal cooling, cycle times decreased by 30% while maintaining part quality.

Special presses or injection systems are normally used for the production of moulded rubber parts. For this purpose, unvulcanized raw rubber or silicone is is injected into a mold cavity and then cooled. Basically, there are no limits for molded parts in terms of geometries, sizes, weights and surface structures.

We supply high-quality technical moulds for injection moulding of thermoplastics materials to companies sectors such as automotive, medical, electrical engineering, small household appliances, hobby, cosmetics and other. High precision, quality control and excellent surfaces are guaranteed, as is continuous and competent technical support.

LUMILOY is an mPPO product based on PPO (polyphenylene oxide) alloyed with HIPS, PA (polyamide) or other resins and has excellent dimensional stability and electrical property.

With HP Multi Jet Fusion technology, we manufacture high-precision plastic components with excellent detail accuracy, high resilience and short production times. MJF technology offers an economical alternative to conventional manufacturing processes and is ideal for functional prototypes and small series in demanding applications. Advantages of Multi Jet Fusion technology: • High-quality, dimensionally stable components - Thin layer thicknesses (80 µm) enable fine details and smooth surfaces. • High strength and durability - Mechanical properties comparable to injection-molded parts, ideal for functional prototypes and end products. • Fast production times - Shorter production cycles enable accelerated product development and economical small series production. • Economic efficiency - Optimized material use and efficient processes reduce costs, especially for complex geometries. • Sustainability - High material yield through recycling of unsintered powder reduces waste. • Excellent mechanical and thermal properties - High wear resistance, good chemical resistance and temperature stability. Material options – PA12 for versatile applications We rely on the tried and tested material PA12, which is characterized by its excellent balance of strength, flexibility and temperature resistance. Thanks to its high density and mechanical resilience, it is suitable for numerous industrial applications. Areas of application for MJF-manufactured components: • Automotive industry – functional components, brackets, prototypes • Mechanical engineering – robust housings, technical components, spare parts • Medical technology – custom-made prostheses, special designs • Electronics & household appliances – functional prototypes, small series
