Mould design Cube mould makes two parts; modular tool needs no tie bar extension

Zahoransky will use the opportunity of K 2013 to demonstrate a TIM stack mould unit consisting of two mould halves with a central rotary cube, which allows two different parts to be made on a single mould.

According to the company, the special features of this new patented system are the two mounting platens outside the mould, allowing complex mounting processes to be worked down outside the two mould halves in the easiest possible way. As a result, the machine cycle times are said to be shorter. Moreover, the complexity of the mould is reduced owing to the outside mounting work, the supplier said.

The TIM Light mould, called the little brother of the TIM mould, uses a modular two-platen mould in place of the cube mould. This means that no tie bar extension, generally a must in cube moulds, is needed in the injection moulding machine, the company said. The main benefit is said to be that instead of special machines, only standard injection moulding machines are needed for TIM Light.

Additionally, the moulding assembly in the TIM Light takes place independently outside the mould on external movable platens. The mould cycle is only moderately longer than the mould platens retracting into the mould, Zahoransky explained.
