Polymer powder range for SLS market

Velox GmbH distributor of Axalta Polymer Powders’ Coathylene range, is expanding its plastics product portfolio to include Coathylene SB0426-R.
Velox
The Coathylene range is generally used as an anti-shrinkage agent for hot curing in the composites market. This polystyrene powder grade has been developed specifically for use in Selective Laser Sintering (SLS).

Growing technology
Selective Laser Sintering (SLS) is one of several additive-manufacturing techniques. This promising technology uses laser energy to fuse powdered material, building up shapes layer by layer. The latest development in SLS technology has led to increased production efficiency and allows companies to produce not only prototypes or complex parts but also small series. Offering plastics powders engineered for SLS technology now allows Velox to support its customers’ projects from start to finish.

About Axalta Polymer Powders
With 50 years of experience and a worldwide presence, Axalta Polymer Powders has established itself as the global leader in the formulation and production of ultra-fine thermoplastic powders. Proprietary precipitation and micronization process technologies compatible with a wide range of polymer chemistries enable an extensive selection of product functionalities and particle size distributions.
Axalta Polymer Powders Switzerland Sàrl is the new name of DuPont Polymer Powders Swizerland Sàrl since DuPont Performance Coatings was acquired by The Carlyle Group on February 1, 2013.

Springmann focuses on watch industry…

..and high precision operations. At this year’s EPHJ on booth E42 visitors will be able to discover three different technologies dedicated to highly demanding fields like watch industry and others.

There are always new ways to realize parts or operations and this year’s highlight at Spingmann’s booth will be

  • SLS (selective laser sintering) with precious material
  • Industrial polishing for small parts
  • Two side grinding

 

SLS – still little known technology
The principle of building the parts is simple, a thin layer of metal powder is deposited on the working surface (250 mm x 250 mm), and a laser moves in X and in Y to merge metal on selected locations. Once the “cut” at this level of the part is fully sintered, a new layer of material is deposited and the laser moves to selectively sinter metal at required locations. The part is thus constructed layer by layer. Huge advantage, shapes are not limited by conventional technologies of machining by material removal.
A new world of possible parts opens…

1- digital model of the part, 2-deposition of the first layer of powder, 3-fusion of the powder in the cross-section of the part, 4 – platform goes down, 5-deposition of a new layer of powder, 6 – the operation is repeated until the part is completed (fusion, filing, lowering), 7-elimination of the non-melted material, 8-the part is complete.

To be discovered on Springmann’s booth at EPHJ from June 5 to 8 in Geneva. Customers of the company and interested people can ask for entrance tickets at [email protected] or by phone on +41 32 729 11 29.
