TCB-Arrow Invest in New Krauss Maffei Machines

In line with their continued investment plans, TCB-Arrow have taken delivery of three new injection moulding machines to complement their existing equipment. These consist of a 130 tonne and two 80 tonne Krauss Maffei machines.

In the last 3 years, TCB-Arrow have invested over £500k in new plant and equipment, demonstrating their continued commitment to their business and customers.


With servo driven hydraulic pumps on all three machines, TCB-Arrow expect to see a 40% energy saving over older machines. This is not only in line with their environmental policy and objectives, but it provides a real commercial saving that will be passed onto their customers.

Control and Repeatability

These new machines are very accurate in operation. Injection volumes and speeds are so accurately controlled that they are able to achieve injection times between shots that are consistent to within 0.01 seconds. Combining this with very accurate injection volumes through screw positions measured to 0.01mm, excellent repeatability is achieved between cycles. All of the variable settings are saved in the machine SSDs or on USB sticks; these can then be shared between machines, ensuring that jobs can be put up and repeated accurately from batch to batch, also saving valuable setup time.

Quality Control and Validation

With many of TCB-Arrow’s customers requiring process validation studies to be performed, they comfortably achieve these tight validations through machine accuracy and repeatability.  They work to FDA process validation formats, conducting installation, operational and production qualification validations (IQ, OQ & PQ).
