Fluoropolymer compounds

Colorant Chromatics produces a full range of high quality colour concentrates, speciality compounds, pigment dispersions and inks for processors of fluoropolymers and high performance plastics. The company is promoting a new range of reinforced fluoropolymer compounds, in particular its compounds for foaming of PVdF; carbon fibre compounds in PVdF, ETFE, ECTFE and PFA; glass fibre compounds in ETFE and PFA; cross-linkable ETFE (X-ETFE) and PVdF (X-PVdF), and PEEK compounds. extensive melt-processable product line includes colour concentrates and compounds for polymers including FEP, ETFE, PFA, PVdF, ECTFE, MFA, THV, PEEK, and polysulfone (PES, PSU and PPSU). The colour concentrates are offered in various pigment strengths and resin viscosities. In addition to its standard line of colours and compounds, the company offers special services such as colour matching, pre-colouring and custom compounding, and supplies a full range of pigment dispersions for PTFE extrusion, as well as printing and striping inks for FEP, ETFE, PFA, PVdF and PTFE.

When you are looking for a robust and powerful timing belt drive that also is a paradigm for successful industrial design, you cannot help checking out the Joachim Uhing KG portfolio. The motorised AZ 1040 succeeds the tried and tested AZ 2004 the company, based at Mielkendorf, has been selling since 1991. The AZ 1040 has the potential to quickly take the place of its predecessor in the Uhing product range and to become the bestseller. Even at first glance, it convinces by its design, giving you an idea of optimal applicability: the one-piece profile with integrated carriage guide allows for greater free stroke lengths than were possible with AZ 2004. Compared to the previous model, several installation and attachment options were added to the AZ 1040. For this purpose, head pieces made of the same profile as the drive itself were integrated. The T-slots are an integral part of the profile and facilitate mounting of additional attachments. Slide blocks can be inserted laterally. Like all Uhing timing belt drives, the AZ 1040 is made of a bend-proof and torsion-proof aluminium profile. A belt lock fastened to the roller-mounted load carriage transmits the power from the timing belt to the load carriage running on round, corrosion-proof and hardened The PWC-S cleaning system incorporates new technology which enables normal plant water to be converted into a unique multi-action high pressure wetting/ displace/flush cleaning liquid used to clean drawn wire at high-speed, providing a smooth and glossy wire finish in plating quality. The system simultaneously performs surface cleaning and polishing, in-line with wire drawing machines at 6 to 12 m/s (1,200 to 2,400ft/min). Exceptional cleanliness obtained permits wire direct brass coating, copper coating, and wire cleaning prior to heat treatment and coating applications including patenting, annealing, painting, plastic coating, etc.

guide bars mounted on the aluminium profile. Uhing offers the new timing belt drive as a complete pre-assembled unit with motor, making assembly and installation fast and smooth. The AZ1040 proves to be particularly practical because its motor can be mounted in several positions. This feature more or less excludes space issues design engineers have often to deal with when integrating such units. During operation, the AZ 1040 proves to be particularly robust and powerful. The carriage covers a distance of 200mm per shaft rotation. The motorised drive features a maximum traversing speed of 5/s and an idling torque of 0.7Nm. The dead weight of the drive for a stroke of 0mm is 9.1kg, the weight per 100mm stroke is 0.9kg. The carriage weighs 2.3kg. JoachimUhing KG GmbH & Co – Germany Fax : +49 434 790 640

Wire cleaning: Drawn wire in plating quality Advertorial on behalf of Decalub

▲ ▲ Wire cleaning by PWC-S system

The PWC-S system effectively loosens and removes lubricant residue from the base material and is particularly recommended for cleaning applications with wires drawn upon severe conditions resulting in increased heat and burned lubricant tightly bound to the wire surface and embedded in microscopic cracks.
