Variothermal temperature control using BFMOLD™ technology DE-TO-72
Abstract
A German institute has developed a new temperature control technology for injection moulding processes. It enables extremely quick and even cooling of the mould areas, especially for wide, flat parts, with the benefit of short cycle times, prevention of warpage, sink marks and joint lines as well as a reduction in tension. Users of injection moulding technology are sought to optimize their processes by applying the technology.
Description
In injection moulding technology, mould temperature control has never been more important than today. Optimising the cycle time and increasing the component quality by means of variothermal processes are among the issues to be addressed by modern temperature control technology.

A German institute has developed a new temperature control technology for injection moulding processes. BFMOLD ™ technology can not only be used for the cooling of flat components but also in combination with variothermal temperature control using water. In this way, this technology allows for short heating and cooling times.

In contrast to moulds with conventional tempering channels, BFMOLD™ technology utilizes the entire space underneath the cavity for heating and cooling. The ball filling favors a highly efficient flow through the tempering channel and can at the same time be positioned very close to the surface of the cavity. This makes extremely quick and even cooling of the mould areas possible, especially for wide, flat parts, with the benefit of short cycle times, prevention of warpage, sink marks and joint lines as well as a reduction in tension.
Innovation and advantages
- Cost effective and simple manufacturing of moulds especially for wide,
flat parts
- Production of high-gloss surfaces without weld lines, warpage and sink
marks
- Short cycle times
Technical specifications
BFMOLD ™ technology is particularly applicable to production of large parts in amorphous plastics such as ABS, ABS/PC blends. Although limited to relatively flat parts with shallow draws, there is a good potential in automotive and telecommunication applications.
