Injection moulding

Precision in every part. Quality and reliability throughout the entire production process.
Our capacity allows us to handle high volumes of millions of parts. Quite simply, we follow your product’s life cycle, whatever the need.

Low volumes and high volumes – we have the capacity

We scale up the manufacturing to meet your need. From prototype to full series production.
Prototal Industries’ machinery plant has more than 80 automated injection moulding machines at its disposal.

Manufacturing is undertaken as near to you as possible to minimise transport.

Quality-assured process

Before manufacture, we simulate the injection moulding so that we can detect any defects and risks with the fabrication at an early stage. We then fabricate the die and you receive the resulting samples and logs. We then continue measuring and checking constantly throughout the entire manufacturing process.

Further processing

2K injection moulding – The quantity of parts determines the choice of manual or proper double injection moulding. Soft, ergonomic grip surfaces are one of the most common applications of this method.

Tampon printing – Elegant process for decorating plastic parts; a lot of freedom in terms of choice of colour. Printing is performed in-line or as post-manufacturing processing.

Hot embossing – An alternative to tampon printing for decorating injection-moulded castings; best performed in-line. This method enables a decorative finish with high-sheen, metallic colours, for instance.

IML – In Mould Labelling – A decorative label is placed in the die with the aid of a robot; after injection moulding, the label is an integrated part of the final product.

Ultrasonic welding – Choice of thermoplastic, geometry and design of energy inverter are some of the factors that affect the welded end result. A correctly executed weld results in a join that is stronger than the surrounding material.

Guidelines

The choice of material affects the shrinkage allowance required from the die.
The choice of material can affect the geometrical accuracy of the part.
The part’s construction can affect the geometrical accuracy and the risk of sink marks.
If we are involved early on the project, we can help you by providing critical product assessments to ensure the part is better suited for quality-assured manufacture.
The quantity of parts to be manufactured will impact on the die solution. Are they prototypes, low-volume series or high-volume runs?
