Moldagem por injeção elétrica com qualidade de repetição

Rentabilizar ao máximo a sua máquina de moldagem por injeção elétrica

No que diz respeito à moldagem por injeção, as principais exigências dos fabricantes são a consistência, repetição e precisão. Estes aspetos são combinados com uma qualidade melhorada das peças e com a capacidade de obter precisão na moldagem através da utilização de conjuntos de parâmetros consistentes que, uma vez definidos, são monitorizados e controlados pela máquina. Deste modo, obtém sempre os mesmos resultados de alta qualidade e, tendo em conta uma introdução manual extremamente reduzida, também beneficia de tempos de disponibilidade e de tempos do ciclo melhorados.

Useful technologies for the injection moulding process

Consistent accuracy

Cutting-edge machines achieve high levels of stability and repetitive accuracy through sampling intervals of under 20 microseconds.

Wear monitoring

Machines capable of measuring backflow, provide operators with the opportunity to change the no-return valve before problems with the injection moulding process lead to poor parts quality.

Precise plasticising

Achieving extremely consistent part weights even when viscosities are varied requires precise digital control of the screw.

Prevent mould damage

To avoid costly repairs and protect the mould clamp and ejector mechanisms, intelligent functions on some injection moulding machines monitor the torque applied to them, preventing damage should this increase beyond certain parameters.

Improve your cycle times

To ensure you benefit from improved cycle times, machines should come with functions such as pre-injection, pre-ejection and parallel movements.

Adding inserts is easy

More complex applications often require inserts or labels to be added. As part of a moulding cell, some state-of-the-art machines can be easily supplemented with robots that pick and place these inserts very precisely at high speed.

Mould validation

Validating your moulds guarantees perfect moulding parameters, ensuring you get acheive the best possible results right from the start.

Prevent mistakes ahead of time

Use a mould test to define the best injection moulding process before you start production. This ensures that all parameters correspond perfectly and you obtain the best results from your process.

Produce different types of part on one machine

Trade moulders and manufacturers no longer need different machines to produce different kinds of parts. Some injection moulding machines are so versatile that they will produce anything from extremely precise and delicate items like camera lenses to products that require high levels of exertive force to produce (such as battery cases).

Electric injection moulding for specific applications

Automotive

For varied applications, such as automotive, more versatile machines are equipped with over six different screws. To ensure they can mould products with differing material characteristics, specifications should also include high duty injection units, active gas venting, sensitive mould protection and multi cavity pressure channels.

Sensitive moulding

To prevent air and burn problems from occurring during the injection moulding process, some machines are equipped with a sensitive pre-injection function. This useful feature is ideal for sensitive moulding applications such as the production of light guides.

Electrical

To produce intricate electrical parts, features such as high-speed acceleration injection control, active gas venting, intelligent plasticising control, sensitive mould production and multi cavity pressure channels are extremely useful.

Medical

Given the critical nature of medical products, smart functionality designed to overcome material inconsistencies and gas issues are essential to ensuring highly consistent moulding and parts quality.

Optical

The production of optical products requires extreme levels of accuracy and consistency. The nature of these items requires machines to be capable of maintaining long high pressure holding times and providing exacting levels of control on both low and high speed pressure.
