Safely Transferring Your Custom Silicone Molds: A Guide to Changing Manufacturers

In B2B manufacturing, switching suppliers is often viewed as a logistical nightmare. However, staying with a silicone manufacturer that consistently delivers high defect rates, unexpected price hikes, or delayed shipments will ultimately cost your brand far more than a transition.

If you already have established production volume but are frustrated with your current supplier, you do not have to start from scratch. At Reemane, we regularly help procurement teams and engineers successfully transfer their existing custom silicone molds to our facility. Here is our structured process for taking over your tooling and stabilizing your supply chain with zero production downtime.

1. Tooling Compatibility and Assessment

The biggest fear buyers have is that a new factory will force them to pay for a brand-new mold. In most cases, this is unnecessary. As long as you legally own the mold, it can be relocated.

Before you ship anything, Reemane’s tooling engineers will conduct a remote assessment. We require:

• Photos and overall dimensions of the existing mold (open and closed).
• Details on the mold material (e.g., P20 or S136 steel).
• The current molding process (Compression or LSR Injection) and cavity count.

Because we operate a diverse range of hydraulic presses and injection machines, we can typically adapt standard molds to our equipment using custom mounting plates. If the mold is compatible, we can take it over immediately.

2. The “Bridge Production” Strategy (Zero Downtime)

You cannot afford to halt your assembly line while a mold is in transit. To prevent stockouts, we strongly recommend a “Bridge Production” strategy.

Before requesting the mold from your current supplier, place one final, large order with them to build a safety buffer of inventory (typically enough for 4 to 8 weeks). While you consume this buffer stock, the mold is shipped to Reemane, allowing us ample time to set up, test, and validate the tooling without putting your supply chain under pressure.

3. Mold Inspection and Refurbishment

When a mold arrives from a low-end supplier, it is often in poor condition. It may have damaged locating pins, rusted cavities from improper storage, or crushed parting lines that cause excessive flashing.

Before putting the mold on our production floor, it goes straight to our in-house tooling center. We perform a comprehensive deep clean (often using dry ice or sandblasting), polish the cavities, and replace worn hardware. We treat your transferred tool with the same lifetime maintenance guarantee as the molds we build ourselves, ensuring it returns to peak performance.

4. First Article Inspection (FAI) and Material Matching

The final step before mass production resumes is the FAI. We match your original silicone specifications—whether it is a 50 Shore A FDA-grade compound or an IP68 weather-resistant EPDM alternative—and press a sample batch.

We provide you with comprehensive FAI reports and physical samples to ensure the new parts meet or exceed your original 2D drawings. Once approved, we lock in the manufacturing parameters (temperature, pressure, curing time, and material lot), ensuring absolute consistency for all future orders.
