Precision Waterjet Cut Lead Sheet Inserts 0.2mm Tolerance CT Door Assembly

Precision waterjet cut lead sheet inserts are produced on a five axis abrasive waterjet machine that cuts lead without melting it. Unlike shearing or laser cutting, the abrasive jet removes material by erosion, so there is no heat affected zone, no recrystallised edge and no oxide smear along the cut face. The result is an insert that drops into a door frame, a collimator housing or a glass surround with the same fit on the first panel and the five hundredth, without hand filing on the assembly line.

Every job starts from a customer drawing or a step file. Our programmers nest the parts to keep scrap below eight percent on a full lead sheet, then cut from 1 mm to 20 mm plate with the same tolerance band. Holes, slots, radii, step profiles and lead glass rebates can all be produced in one operation, which removes secondary machining and the handling risk that comes with moving soft lead between work centres. Lead is soft and marks easily, so blanks are handled on padded tables and finished parts are wrapped individually before they leave the cutting cell.

• Cold Abrasive Cutting: Waterjet erosion leaves no heat affected zone, so the lead keeps its original grain structure and the cut edge stays bright instead of oxidised.
• Repeatable 0.2 mm Profile: Profile tolerance is held at plus or minus 0.2 mm and hole position at plus or minus 0.1 mm, verified on a coordinate measuring machine before the batch is released.
• Burr Free Edges: Cut faces come off the machine at Ra 3.2 or better with no burr, which removes a manual deburring step from your assembly line.
• One Piece Complex Geometry: Holes, slots, radii and lead glass rebates are cut in a single setup from plate up to 20 mm thick, replacing multiple machining operations.
• Drawing to Part Service: Send a DWG, DXF or step file with the required lead equivalence and we return a nested cutting plan and first article sample for approval before the full run.
• Purity Preserved: We cut only virgin 99.99 percent lead stock, so the attenuation of the finished insert matches the value used in your shielding calculation.

These inserts are used wherever a lead component has to fit a machined assembly rather than hang on a wall. Typical parts include CT and DR door cores, lead glass window surrounds, collimator aperture plates, detector housing gaskets and shield blocks for industrial radiography cabinets. Because the geometry is cut to drawing rather than folded on site, installation time drops and the finished assembly keeps a consistent look from room to room in a hospital project.

The same process suits retrofit work. We can cut replacement inserts from a scan of an existing part when no drawing exists, then match the original lead equivalence and hole pattern so that the door hardware bolts straight back on.

Each insert is wrapped in closed cell foam, stacked in a plywood case and shipped with a dimensional inspection report that lists every critical dimension against the drawing. Small consignments travel by air express; full sets for a hospital project are crated on pallets and can be delivered to site in installation sequence.

Quality control follows GB/T 19001-2016 and the plant holds CE certification for radiation protection products. First article inspection is mandatory on every new part number, and a sample from each production batch is retained for twenty four months. If a dimension drifts outside the agreed tolerance, the batch is re-cut at our cost before it is packed.
