Why Drain Position Should Be Frozen in the Drawing Before Production
Quick Answer Drain position should be frozen before production because changing it can affect: For a handmade sink, drain position may be relatively flexible before fabrication is finalized. For a pressed sink, the available position can depend on the mold and bottom geometry. “Rear drain” or “center drain” is not enough for a custom project. […]
What Buyers Should Check Before Approving a Workstation Sink
Quick Answer Before approving a workstation sink sample, check the sink and accessories as one system. The critical points are: A workstation sink can pass basic sink inspection and still fail in use if the accessories rock, bind, fall through the ledge or interfere with the drain. Approve the complete workstation system, not the sink […]
How to Compare Two Stainless Steel Sink Quotations
Quick Answer Before comparing two sink prices, make sure both suppliers are quoting the same: If one supplier quotes a 1.2 mm handmade sink with a complete workstation accessory set and individual foam packing, while another quotes a pressed sink with drain only, the lower price tells you very little. Normalize the specification first. Compare […]
How to Audit a Stainless Steel Kitchen Sink Factory
Quick Answer To verify whether a kitchen sink supplier is a real manufacturer, check whether its factory evidence matches the production method it claims to offer. For stainless steel sinks, verify: The key question is not: Does the factory look busy? It is: Can the equipment, materials, people and records you see actually produce the […]
Why Pressed Sink MOQ Is Usually Higher Than Handmade Sink MOQ
Quick Answer Pressed sinks usually have a higher practical MOQ because production depends on: Handmade sinks rely more on flexible sheet fabrication — cutting, bending, welding and polishing — so smaller quantities of one model are often easier to schedule. That is why: Pressed MOQ is driven more by production-run efficiency, while handmade MOQ is […]
Existing Mold vs New Sink Tooling: What Buyers Should Know
Quick Answer Use an existing pressed-sink mold when the available size, bowl depth, radius, rim and drain layout are already close to your target product. Open new tooling when those dimensions or product geometry are important enough that an existing mold would require too many compromises. The decision usually comes down to: Existing molds usually […]
What Should Be Included in a Kitchen Sink Golden Sample Approval?
Quick Answer A kitchen sink golden sample approval should freeze more than the physical sink. Before mass production, confirm: The physical sample is only one reference. For repeat production, the stronger control is: Golden Sample + Approved Drawing + Specification Record + Packing Reference If only the sample is approved and the written specification remains […]
Why Two 16-Gauge Sinks Can Have Different Weight
Quick Answer Two sinks can both be sold as 16 gauge and still have different weight. The difference can come from: The key point is: Gauge describes material thickness. Weight describes the whole sink. A heavier sink does not automatically prove that every part of the stainless steel is thicker. If thickness matters, compare actual […]
How to Specify Stainless Steel Sink Thickness in an RFQ?
Quick Answer For a stainless steel sink RFQ, specify four things clearly: For a handmade sink, different structural parts should be listed separately if they use different thicknesses. For a pressed sink, the starting sheet thickness and finished thickness are not automatically the same because deep drawing stretches the stainless steel. A clearer RFQ is: […]
