When it really comes down to what’s on the outside: Injection moulding tools for the packaging industry

The plastic packaging industry is characterised by the shortest possible cycle times and, at the same time, enormously long service lives of moulds. It’s quite fitting then, that injection moulding tools from Hofmann – Ihr Impulsgeber fulfil precisely these requirements.

In addition to multi-cavity moulds, it is primarily multi-daylight mould technology which offers huge potential for cost savings in part production here. Bucket lids, for example, can be efficiently produced using this technology.

Multi-component technology is also becoming increasingly important in packaging technology. Hofmann – Ihr Impulsgeber is able to apply its many years of experience in the injection of sealing elements for car parts here. Moulds for high-quality beer and wine bottles, as well as buckets and boxes, have already been developed.

Using special LaserCUSING® technology, Hofmann – Ihr Impulsgeber is able to offer completely new options for the high-performance moulds of the packaging industry. The LaserCUSING® process makes it possible to produce mould inserts with intensive conformal temperature control, which reduces the cycle time considerably and increases your efficiency.

Our machine engineering division also offers solutions precisely matched to your mould. From injection moulding automation to robotic and handling systems, and from gripper systems and equipment to sprue separation, you get everything from a single source with us.

Packaging industry case study: Shower gel and shampoo caps for Gramß GmbH

At a glance:
Construction and development of a 16-compartment, 2-component injection moulding tool for the production of shower gel and shampoo caps for Gramß GmbH.

The customer:
Gramß GmbH is an owner-operated family-run company founded in 1989. The company produces injection-moulded items using state-of-the-art computer-controlled machines. From its company location in Spechtsbrunn, Thuringia, Germany, the company serves national and international customers in the cosmetics, pharmaceutical and foodstuff industries.

The task:
Produce a 16-compartment mould with short cycle times and reliably high quality – that was the task of Hofmann – Ihr Impulsgeber. It was especially important to ensure that the opening and closing of the caps consistently function properly and that the hinge of the cap remain stable.

The solution:
To achieve consistently high quality in cap construction, the specialists at Hofmann – Ihr Impulsgeber designed the mould in such a way that the closing forces in all 16 mould cavities are the same. This harmonisation of the mould guarantees process-reliable manufacturing and flexibility in cap production.

Success:
Hofmann – Ihr Impulsgeber supplied a reliable and fast serial-production mould for the production and fully automatic fitting of shower gel and shampoo caps. This injection moulding tool guaranteed the customer ideal cycle times, increased availability of the mould and high-quality caps.
