Hi all. I am working with a University that has developed a novel and innovative spot welding technology designed to directly address the limitations and challenges of existing resistance spot welding (RSW) and friction stir spot welding (FSSW) techniques. RSSW creates opportunities to create...
Hi all,
Thanks for your responses. The context here - I’m doing some commercial feasibility work with a company that is developing a new component measurement technology designed to overcome the limitations of metrology. Their system will increase the measurability of plastic component features...
Hi all,
Are there any existing systems out there that would take/absorb measured dimensional data from injection molded components and feed it back to the injection molding machine to enable process optimization and valdiation to better control the process?
Appreciate any information you can...

Hi folks,
I am currently working with a client company and we are seeking a cost effective supplier of quality compounded rubber. I'd appreciate any suggestions/referrals to European or Asian suppliers.

Folks,
I am working with a client company who currently buy in a folded enclosed sheet metal panel that is foam filled for insulation purposes. The company buys the panels coloured and has limited colour options on the metal and would therefore like to buy the panel uncoloured and colour...

You should inquire if the moulder is using regrind material as this can affect mechanical properties. Also find out if there's a filler in the material such as glass or a mineral such as talc which cheapens the material and is probably uncall for. I'd be careful when you broach the moulding...
In the current Mobile Telecoms industry, mobile operators are beginning to rollout their 3G networks. With the requirement for more transmission sites and the public objection to signal transmitting installations, operators here in Ireland and the UK are forced by planners to ensure their...
I have seen silicone gel sheets used for medical purpose which can be washed and reused repeatedly with no adverse effects on the stickiness.

Not to forget PC...for extra strenghth and toughness. ASA is marketed on it's ability to retain colour. It has exceptional colour fastness properties and won't fade much over time even in direct sunlight.

There are a few Ian, I'd advise you to subsribe to a publication called the Plastics and Rubber Weekly (PRW) www.prw.com which comes out every thursday and would have the biggest circ in the UK and Ireland. It will have all the info you need on courses, distance learning or otherwise. There are...

This has come up before but I have forgotten how to renumber faces and edges. I have an IGES model that has been cleaned up and prepared for mould splitting. There are about 1700 faces on the part but I have done so much stitching and cleaning that the edge numbers and face numbers...
tomysux,
It's hard to make a call without seeing the geometry of the part. PP and PE are good materials for 'bumping off' threads but a lot of the mechanics in doing it is down to the design of the mold. When you have the design right obviously you can play around with variables like cycle time...
Johnr,
The GE site is good for what you need for the design of snaps....

As Pat has said, almost any amorphous material should meet your stated criteria. Try to select a material which has a comparably low shrinkage value to minimise warpage and try to gate the parts at one end preferably with an edge tab or fan gate.

Have you tried putting a solenoid valve with a pulsing circuit on the line and pulsing the air periodically to avoid clog?
