Resin mother vs steel compression: two mold-making processes

Resin-mother chain (WYD path)

Buyers often collapse this into "make a silicone mold from a 3D print." The steps are separate objects. We write them in order so the RFQ names the right one. The resin mother itself is a WYD quote. A poured RTV glove built around a sculpture is a different WYD process on this plant - not this traveler.

1. Start with a 3D-printed pattern (the master start). That print is the original shape, not the production tool.
2. (Optional) Flip the print into an intermediate silicone mold - a temporary cavity that can take a resin pour. Some shops cast resin from the pattern without this flip; name which object you actually have.
3. Cast a resin mold from the pattern, or from that intermediate silicone if you used one. The resin mold is the mother (母模). It is not the pattern and it is not the finished silicone tray you will sell or run.
4. Use that resin mother to batch-produce trays copied from the mother.

WYD RTV pour-tool (different process, same plant):
   poured RTV glove / pour-tool around a sculpture

We do not have an honest shop still of that exact chain on this floor. Do not read a tray photo or a steel insert as a resin mother. A poured RTV object is a different WYD process - same plant, not this traveler. Send CAD, master, or pattern on the contact form.

Hypothetical: one RFQ names both processes

Hypothetical path - not a named customer file

A buyer sends an STL and writes "resin mother, then steel compression, same PO." We split the objects and quote each path. Both can be WYD. If they actually want a poured RTV glove built around a sculpture as the tool itself, that object is an RTV RFQ on this site. If they need a reusable production tray or an HCR part from a steel tool, we quote those from the contact form or the RFQ file list. We do not mash two processes into one mystery price.

Process-fork FAQ

Is the resin mother the same as the 3D-print master?

No. The 3D print is the pattern (the master start). You may optionally flip that print into an intermediate silicone, then cast a resin mold. That resin mold is the mother used to batch-produce trays. Do not call the resin mother a master.

Does WYD quote the resin-mother batch path?

Yes. The resin mother (树脂母模) is a WYD path on this fork: 3D-print pattern, optional silicone flip, then the mother that batches production trays. Steel / HCR compression is the other WYD path. A poured RTV glove / pour-tool is a different WYD process - same plant, different traveler. Send CAD, master, or pattern on the contact form. DFM review is free. CAD about $50 when the model needs lock.

What WYD objects sit on this fork?

Resin mother (树脂母模) and steel / HCR compression. Also mother-supported platinum production trays, LSR / OEM molded parts, and injection tooling when the drawing is a part. DFM review is free. CAD modification is about $50 when the model needs lock - not a fee on every PO. Soft-tray MOQ about 20. Proto 3-7 business days after CAD lock.

How do I choose between master-based mold making and compression tooling?

The choice depends on the item being produced, its geometry, material, quantity and repeat-order requirements. Send the drawing or master pattern and intended application. We will review the manufacturing route and identify which prototype checks are needed before production tooling is approved.
