Through injection moulding processes, plastic moulded parts can be produced economically and in large quantities. Melted plastic is injected under high pressure into the mould cavities of a tool.
By means of electrical heating, hot-runner systems keep the polymer melt flowing on its way to the cavities.
Automation, Innovation and High Precision Machining: a Mould-Maker Relies on WorkNC
A high-volume mould-maker for the French food processing industry says WorkNC, from Vero Software, is an “irreplaceable” asset to their production process. The software helped them to implement a completely automated workshop, freeing up time to take on new projects.
Tianjin Motor Dies Co. Ltd., founded in 1995, celebrated its twentieth anniversary in April 2015. Currently, Tianjin Motor Dies has more than ten plants in China and has even set up manufacturing facilities in Germany. The company, one of China's largest motor die manufacturers, has now begun to impact the global dies market in earnest.
Anything But A Bottleneck Coordinate Metrology in Toolmaking
The Corvaglia Group based in Eschlikon in eastern Switzerland is a top performer in every sense. The company is a specialist manufacturer of inexpensive caps and closures for PET bottles. Along with plastic injection moulding, toolmaking has a major role to play at Corvaglia. To avoid toolmaking becoming a bottleneck, Corvaglia calls upon technology from Hexagon Metrology: the team uses a DEA GLOBAL coordinate measuring machine with PC-DMIS software for presetting. The advantage: the electrical discharge machining (EDM) equipment can run non-stop as the operatives set-up the parts away from the machines.
Ballerstedt, the renowned plastic-injection moulding company, uses probes and Form Inspect software from m&h when constructing their moulds. Mould inserts can now be made to fit accurately and to be easily replaceable. This shortens downtimes and increases productivity.
Innovation and customer benfit, these are the maxims that have established mould maker Hofmann of Lichtenfels enviable reputation. At Hofmann, measuring workpieces while still clamped on the machine has been an everyday occurrence for over seven years. Using touch probes and software from m&h, Hofmann has improved quality and reliability of the production process while speeding up the manufacturing cycle at the same time.
Measuring contours on the machine tool not only ensures quality but also considerably shortens set-up times and speeds up manufacturing cycles. A mould making and jobbing company reports its experiences using m&h 3D Form Inspect software and proves that quality assurance also reduces manufacturing time.
The mould production of Color Metal produces mould inserts in an automated facility with a large pallet storage on five-axis machining centres by Grob. For this purpose, the tools are calibrated by an m&h laser and checked for tool breakage.
At Jochum, a mould manufacturer, tool length measurements and blade fracture checks are performed on a removable Tool Setter by m&h, even in unmanned shifts. The Tool Setter communicates with the control via the same infrared receiver as the probe.
The contract manufacturer SHW Bearbeitungstechnik GmbH has equipped its machining and turning/milling machines with radio-wave touch probes by m&h and regularly calibrates the machine tables with it. That provides accuracy, and the probes save set-up times and allow for an accelerated and secure production of mostly large and complex cast parts.
An Italian manufacturer of injection moulds provides for clear vision in production through measuring workpieces while still clamped on the machining centres. This is achieved by using German m&h touch probes and software on Japanese machine tools.
More Speed and More Accuracy With Laser Tool Setters
For years, model and mould construction has been measuring using probes and software by m&h. Now tools are also measured in the machine using m&h laser tool setters – with significant improvements in manufacturing.
Measuring workpieces on the machine has become standard practice at the Saxon milling service provider Hofmann & Engel. The possibility to log work directly on the machine has helped win several orders from mould making and single component manufacturers.
