Smart combination of plastics

Combine materials for innovative products and economic production combimelt process M ulti-component injection moulding In the simplest case – multi-colour injection moulding – the combined plastics differ only in colour, to create a specific design. This method involves the processing of different colours, of the same material, in an individual part. However, it is also often necessary to combine different material qualities in a given part. In these cases, the plastics should possess a common adhesive quality to guarantee that the components of the finished part are securely bonded. F...

Multi-component injection moulding ENGEL skinmelt Two-component injection moulding with a special plasticising process: Unlike classic coinjection, the skinmelt process involves fusing the two melts prior to injection. The skin material reaches the cavity first. It is pressed against the cavity walls by the injected second material – the core. The result is sandwich parts with premium quality. Additive processes In this process, two or more components are injected next to or on top of each other in successive steps. Here the individual components form a permanent bond (sequential linking of...

This glazing is lighter, offers total design flexibility and combines perfectly with other materials – including functional integration. Large-surface, low-stress multi-component optical parts Machine with low clamping force thanks to stack moulds A great method for producing large-surface multi-component parts of any kind Flexible design and optimal functional integration in the...

Assembly moulding Suitability & bond strength Seal assembly Parts with an integrated sealing element are produced in a single injection moulding process. A rigid-soft composite is created. One application area is the integration of sealing elements by sequential combination injection moulding. ENGEL combimelt can be used to produce sealing elements both from cured and thermoplastic elastomers. Optimised part properties can be achieved by combining up to 6 components with different properties. Production of assemblies Moveable joints can be created by selecting materials that do not adhere...

Combimelt mould designs Economic and resource-friendly production: ENGEL combimelt allows you to produce parts using different components, safely and efficiently, in one single production step. Depending on the product design and type of application, various mould concepts can provide the desired result.

Rotary table technology Index plate technology The universal, efficient solution for all ENGEL combimelt processes: rotary table technology allows you to meet the most diverse requirements of combination injection moulding with precision and speed. The rotary table is integrated as a fixed module of the moving platen of the ENGEL injection moulding machine. You have the flexibility to use multiple moulds on one production cell. Great flexibility in the product design: The index plate technology is the perfect solution if you want to add components to both sides of the moulded part. The...

Transfer technology Horizontal rotary table technology Whether small batch series, bulky insert parts or special solutions: you can easily transfer moulded parts during the combimelt process using transfer technology. Automation gives you plenty of options: for example, if you want to insert bulky components or efficiently produce 4-component parts on two injection moulding machines. You might want to consider this technology if a rotary table or index plate solution requires a disproportionately large clamping unit. Manufacture moulded parts efficiently on smaller machines. The ENGEL combi...

Core-back technology ENGEL coinjection Cost-effective production of small quantities: core-back technology allows you to produce moulded parts, using several materials, easy and economically. Though the cycle time may increase as a result of the sequential injection moulding process, this technology does not require any manipulation devices during the combimelt process. Furthermore, the relatively compact mould design often makes it possible to use smaller machines. Intelligent optimisation of costs, quality and design: ENGEL coinjection allows you to not only produce parts at a lower cost,...
