The sharp edges on compression clays and some high-end plastics are created by subsequent machining operations after creation, not from the mold design.
Machining china clays is certainly possible (a few very early examples did have sharp edges), but it's not cost-effective to add an expensive post-production finishing step to a product that costs just pennies to produce.
Yep. Paulson uses a lathe type set-up, while CPC's system is more like a grinder.Is the post-mold machining what produces the sort of ‘ridges’ on the rolling edge of some chips?

Some, like CPS, were ordered specifically with beveled edges. They typically make what you ask them to. They have no problem passing the extra cost on.
Somebody that actually orders clay chips from China in our current lifetime might be a better resource.
Thanks for the info guys.
There is someone in Australia looking to design their own chinese clays, like Apache did with majestic and royals.
I mentioned sharp edges would be a win, but didn’t know the ins and outs.
Incorrect -- the CPS chips were not specifically ordered with beveled edges. The manufacturer created the molds with cross-hatching (at our request), but the beveled edges were not part of our submitted design.Some, like CPS, were ordered specifically with beveled edges.
