› Tie bars

Injection-moulding machines are characterised by the clamping force exercised on the mould. The opening and closing mechanism of the mould is a high-tech feature, capable of producing high forces. Tie bars are used both for guiding the mould and for transferring the clamping force.

Tie bars must meet stringent requirements: they must be capable of withstanding the extremely high forces acting on their inside.
No matter how careful the manufacturing of die bases, tie bars cracking, a frequent problem in injection moulding, can always occur due to bad alignment or wrong strain.

We usually are capable of repairing a broken or cracked tie bars in a sound manner.
If repairing is impossible, we can always offer a new component. For new tie bars the maximum diameter is 200mm.
