We provide optional post-processing services that save time behind the bench and money, from simple flush-cuts, flow-gate removal and enhanced surface texture treatments.
We offer two simple optional post-processing services, designed to save you time, labour, gold loss and headaches. They're charged separately from casting and metal processing fees, so you can see exactly where your money’s going. No bundling, no guesswork. Some of our clients prefer a "clip n ship" service (no post-processing options) whilst others want their castings "clean n lean" (with post-processing), we cater for both, without playing hide-and-seek with your margins.
After casting, all casting trees are acid-bathed to remove investment powder and oxides. From there, we perform a premium surface treatment using a precision-calibrated vapour honing system that combines nano micro-glass beads, water, and high-pressure air. This process gently removes the raw casting skin, including all surface oxides, leaving a smooth, ultra-satin finish.
This is a true micro-abrasive process, removing an average of 1 micron across the entire piece. We refuse to use coarse grits to create a deeper shine, as that only masks surface porosity, leaving your jewellers to discover it once sanding or filing begins. If there’s any surface porosity present in our castings (which is rare), our fine media will reveal it, not hide it.
Our flush-cut service reduces the main feeder sprue length from the standard 5 - 10mm length down to around 2.00mm from the casted item. We do not go any closer as we do not want to risk damaging your castings. Using industrial-grade equipment and precision German-made flush-cutting blades, we handle the heavy work, but note, this is not a full de-sprue; filing and sanding is still required on your end.
For an average 18k gold ring, we remove roughly 0.70 - 1.30g of gold (depending on the thickness of the feeder sprue). You’re not billed for this material as we retain it, which lowers your invoice, cuts down on your own refining, and streamlines production as it allows your jeweller to go straight to filing.
Ideal for workshops processing multiple jobs or working under pressure, but just as useful for one-offs where time and metal efficiency count.
Our Cut n Save Service, is designed to safely remove the internal flow gates from your casted items without damaging or deforming them. We use a micro-motor hand piece with a small circular saw (similar thickness of a jewellers saw blade), to cut the internal flow gates off from a 45 degree angle.
We leave approximately 2.00 - 3.00mm of material at each contact point leaving them ready for filing, sanding and polishing, this is done to ensure we do not damage your castings profile and so the motor micro's shaft does not touch your item. Our standard fee for this services covers a regular sized ring with up to 4 contact points. Items with more than 4 contact points or large bangles need to be quoted.
For a typical average sized 18 karat gold ring with four contact points at 1.4mm thickness, our Cut n Save Service removes approximately 0.70 - 1.0 grams of gold. The gold removed is not invoiced (as we keep this gold). This saves you time and eliminates the losses associated with refining, on larger pieces such as bangles, this service can account for a gold saving of 20 - 40 grams.
