There is now opportunity for a self motivated individual to join our sales team.
This is a full time permanent position, with full support and training given.
 
For further details please contact wkh-accounts@btconnect.com

Focus on Polypropylene / PPC

Polypropylene is the most versatile of all industrial plastics , especially for fabrications.
With a service temperature of minus 5 to plus 100 deg C and excellent chemical resistance it hits the spot on most industrial plastics fabrications.
One of the hardest and stiffest polyolefine make Polypropylene great for Chemical Tanks / Dosing Cabinets / dosing skids / Bunds and splash Guards.
 
Polypropylene will withstand repeat steam cleaning and is approved for contact with food. Our team at WKH GROUP can heat bend / form and extrusion weld the Polypropylene sheet which is available in Beige grey / Natural and Black. Fleece or fabric backed sheets are available for GRP lamination as also are fire retardant grades.
 
We also machine ( CNC and conventional turning / milling and routing ) all industrial plastics including Polypropylene PPC / PPH  available in rod and block stock shapes.
 
Full specification sheets available on request.

Cleaning Compatibility Testing of Materials

Here at WKH we now have a designated area for compatibility testing of certain materials, mostly clear Polycarbonates and Acrylics ( including ATEX complying PC 350 / AC300 & Lead Acrylic H8 to H70 Radiation resisting / shielding ) with Bonding and cleaning products.

This is useful for customers who need to be confident about the care of their product when regular cleaning is required  i.e Cast Acrylic isolators for the clean air Industry & screens or visors where optical clarity is crucial.

We currently have spare capacity on CNC & Conventional machining / Turning and milling.
 
We also stock a large range of industrial / performance plastics including ATEX directive complying materials. Industrial Plastics

CNC Machining of Elliptical Glove Ports

We can bond cast acrylic elliptical glove ports to lead filled acrylic ( H8 to H70 ) and to lead filled glass, taking into account any thermal expansion issues .
 
Videos below show CNC machining of elliptical glove ports.
 
 




 

REMEMBER we have good lead times on all machining of industrial plastics, conventional turning and milling and CNC machining.

Please contact us with your requirements.

Polyethylene HD 500 grade Seal housings

WKH GROUP  Are always looking for new products / technology and techniques to help our customers achieve the best possible results for their engineering requirements.

IE . Polyethylene HD 500 grade Seal housings can now be produced at over 150 mm long by 1250 mm diameter this is due to the item being machined in layers and bonding together backed by a welding procedure . This means holes / grooves / channels / pockets / inlets can be introduced where before it was not possible .
