Injection Moulding

Injection moulding is the core business of KB Components and the most common method of mass-manufacturing plastic components. It is a highly effective process for producing large numbers of identical parts at a reasonable cost. Our product portfolio covers everything from high-precision engineering components to disposable consumer goods. As a KB Components customer, you are offered assistance from engineering and design to industrialization and mass production.

Technology

Injection moulding

Well-established standard procedure for manufacturing of plastic parts.

The KBC group has injection moulding machines with clamping forces of 25-2700 tonnes.

 

Injection Compression Moulding

The philosophy of injection-compression mouldings – the injection of thermoplastic polymer melts into a slightly opened mould with simultaneous or subsequent compression by an additional clamping stroke.

We use a technology in which the additional stroke is accomplished via an integrated hydraulic booster inside the mould.

 

Compression moulding using ICM

Here, we use the injection moulding machine to create the compression.

First, the material is injected when the tool is open. When 80% of the tool is filled, the tool is closed and the final step is compression.

This method is commonly used for thin wall thicknesses and long flow paths.

(Creates less internal stress and reduced warpage.)

 

Back injection moulding on textiles

Multilayer polyester fabric inserted in tool.

Back injection with PC/ABS.

 

2K injection moulding

There are different methods for injecting two chemically compatible materials.

Rotating tool (genuine 2K solution optimum condition).

Rotating with index plate (genuine 2K solution optimum condition).

Move with robot into second insert (semi-genuine 2K solution).

Pre-produced part components put into 2nd mould and over-injected by second material (false 2K).

The KBC Group has 2K injection moulding machines in clamping forces from 80-1000 tonnes.

 

Inserts

Commonly used when high torque is required on threads/screw.

The inserts may be over-moulded or mounted after injection.

Our unique offer

KB Components differs from most of our competitors by having a focused approach to injection moulding technologies, including material technology and design optimization of both the part and the process. By combining our global resources, we give you access not only to a global manufacturing set-up but also to our internal material labs, measuring centres and production technology teams. When your business grows, we have the resources to grow with you and to follow your globalization by providing local production in Asia, Europe and North America. If your product will be assembled with other parts, we also offer complete solutions for production and assembly. Most of the time, this is integrated with the injection moulding operation, using the most modern robot technologies in order to create a cost-efficient production set-up.

At the same time, you can rely on our Code of Conduct, in which we pledge to follow the most stringent regulations for environmental protection and work safety. Apart from being certified according to environmental standards, all our units are also recognized as a “Great Place to Work”, with a vast majority of employees showing high work satisfaction and engagement – to the benefit of all our customers.

Our strategy has proven to be successful and is based on:
A Global Footprint, Technological Leadership and Operational Excellence

Together with our customers, we create “Value Through Innovation”
