Injection-moulding tools from MHT AG have been designed for manufacturing top-quality components on a permanent basis. Since our customers are invariably striving for sustained competitiveness, we offer them overhauls at regular intervals and maintenance routines as part of our Lifecycle Service. MHT has developed tailor-made overhaul programs for the melt-carrying hot-runner system which is crucially important for maintaining top product quality. In this way, we not only increase your injection-moulding tool’s useful lifetime, we also spare you the nightmare of a “complete failure”.
Why overhauling the hot runner is important
It is recommended – and indeed necessary – to overhaul your hot tool side at regular intervals for two reasons: Firstly, during operation soiling accumulates at the valve gate’s functional elements and between the tool plates. Deposits of PET dust throughout the entire interior compartment are typical for injection-moulding tools that handle PET. Secondly, components like valve pins, nozzle tips and insulations, plus sealing rings, are subject to continuous wear and tear.
By removing such deposits and replacing a few functional elements, our service technicians are able to restore the gate to as-new condition, enabling you to achieve quality levels similar to those obtained when the hot runner was new.
Tailor-made or predefined stages
No matter whether it is a hot runner from MHT or from a competitor: We will be pleased to have a look at it beforehand. After dismantling and inspecting the system, we will give you a list of the measures required for restoring original production output levels.
Depending on the number of cycles your tool has clocked up and its maintenance status, we offer a variety of predefined maintenance stages, ranging from a small overhaul right through to a general overhaul after six to eight years. Maintenance packages customised to meet your specific needs will factor in your utilisation patterns, the hot-runner system’s operating time, your quality aspirations and your budget. Our after-sales and service support team will be pleased to assist you in drawing up a tailor-made overhaul package for you. We use exclusively original MHT components, thus achieving optimum levels of productivity and performance.
