news Promolding 3D prints moulds

Netherlands-based design and engineering specialist Promolding has added a 3D printed mould division to provide fast-turnaround delivery of functional short run injection moulded parts. The PRIM service uses an Object500 Connex 3D printer from Stratasys to produce the mould inserts, which it claims reduces mould lead times by 93%. The company said it recently used the Objet Polyjet 3D printing technology in the development of a fibre optic sensor housing for geoscience firm Fugro. The project called for the production of more than 50 samples in final product materials, including PP and PBT resins and TPEs. “PRIM is available to our customers as an additional

Switzerland’s Datwyler Group has acquired Germany-based Ott, a specialist in injection moulding of thermoplastic and liquid silicone (LSR). Datwyler, which makes

electronic technical components and sealing systems, said Ott will become part of its Sealing Solutions business and will strengthen its ability to service customers in the automotive and healthcare sectors. The deal is expected to close this month. ❙

We have come a long way and we’ll continue to explore further applications in which PolyJet 3D printing can enhance our offering.”

“Additive manufacturing has the power to transform business models and Pro- molding is a prime example,” said Andy Middleton, General Manager EMEA at Stratasys. “In the case of injection moulding, 3D printed injection moulds are redefining the price-performance benchmark for low volume production, giving manufacturers the

Developed with Boeing, the Stratasys Infinite-Build 3D Demonstrator turns 3D printing technology through 90° to print on a vertical plane. It is designed for production of large lightweight, thermoplas- tic parts for the aerospace and automotive industries. The Robotic Composite 3D Demonstrator came out of work with Siemens and uses robotics to eliminate manual processing. ❙

Total launches PCR recycled HDPE

Total has launched a new range of HDPE circular compounds with high levels of post-consumer recyclate (PCR) content for the packaging sector. The company claims the new grades offer

performance equal to or exceeding that of virgin resin and are suitable for rigid packaging items such as blow moulded bottles and injection moulded crates. The range consists of natural colour HDPE polymer products containing 25% or 50% PCR content. Total says it will have 20,000 tonnes/ year of capacity onstream by the end of 2017. The PCR content is sourced from household waste collected in Western European countries, recycled by partner companies, and decontaminated at Total’s Antwerp site to ensure it is odour-free. Total then compounds the recycled resin with virgin HDPE to compensate for any lack of performance and consistency in the PCR. ❙
