custom rubber injection molding

Custom Rubber Injection Molding Sourcing is an independent sourcing partner for wearable OEMs. Name the insert, Shore A window, LSR versus HCR choice, and US destination so candidate plants return wholesale numbers on the same traveler, not three incompatible chemistries.

01

HCR rubber

High-consistency stock for thicker strap wings and buckle pads. Record mill-mixed Shore A and oven hours on the traveler.

02

LSR / LIM

Liquid silicone on cold-runner cavities for skin-contact straps. State viscosity, pigment, and whether a post-cure cycle is written before T1.

Get Quote →
03

Overmolding

Strap rubber onto plastic or metal buckle inserts. Identify insert owner, primer, and the peel method you will score.

Get Quote →
04

Tooling class

Aluminum strap tools versus steel production cavities. Keep NRE, cavity count, and assumed shot life off the piece line.

Get Quote →
05

Inspection pack

FAI, Shore durometer, flash map, and the post-cure cycle written on the traveler. A plant logo is not that pack.

What a wearable strap overmold brief must freeze

These six locks keep a custom rubber injection molding RFQ from mixing LSR and HCR quotes as if they were the same chemistry.

A

Drawing revision

Name the strap STEP/PDF letter and any buckle redline. Unversioned skins produce split cavity quotes.

B

LSR versus HCR

State which chemistry belongs on the skin-contact face. Grade substitutes stay marked open until you accept them.

C

Draft and gate

Record draft, parting line, gate vestige, and knit-line zones that will sit against skin.

D

Quantity layers

Separate T0/T1 wearable samples, first production lot, and EAU so tool steel is not guessed.

E

Post-cure on the traveler

Write oven temperature, hours, and lot ID on the traveler. A verbal “we post-cure” is not a record.

F

Landed basis

Write destination, Incoterm, and whether duties sit inside the quoted strap number.

Inquiry starting points, not stocked straps

Each card opens an RFQ cluster. Shot weight, adhesion, and tooling life remain plant replies, not inventory on this desk.

A wearable briefing example, not a named customer claim

“We needed three plants to quote the same strap overmold revision, including LSR versus HCR, T1 sample count, peel method, post-cure hours on the traveler, and DDP Austin, before anyone ranked piece price.”

Procurement scenario used as a briefing example. This desk does not publish verified customer names, plant counts, or savings percentages.

Questions wearable buyers ask before the first RFQ

LSR or HCR for this strap overmold?

LSR usually wins flash control, pigment, and skin comfort on a thin strap. HCR often wins thicker wings, mill-mixed hardness, and a lower material line. Put the chemistry on the traveler so factories do not quote both as one cell.

Is this desk a rubber plant?

No. Custom Rubber Injection Molding Sourcing is an independent matching desk. Certificates, press tonnage, and oven charts stay with the supplier that issues them.

How is FREE sourcing support decided?

Eligible support may be available up to 3% after review. Eligibility applies to qualified business buyers and is confirmed after we review your product, quantity, destination, and sourcing requirements.

Why must post-cure sit on the traveler?

Wearable lots that skip a written oven cycle can pass first Shore checks and later bloom or smell. Ask each bidder to print temperature, hours, and lot ID on the traveler that travels with T1.

Soft tooling or steel tooling?

Aluminum or MUD tools can be faster for T0/T1 strap samples. Steel tools matter when EAU, flash at the buckle, and amortized piece price dominate. Ask each bidder to state assumed shot life.

Where do I send CAD?

This site has no upload field. After the RFQ, send STEP/PDF on the reply channel we confirm so revision control stays on one thread.

Submit the strap brief so factories can quote wholesale

Write chemistry, Shore A, insert source, post-cure hours, quantity, and destination in one packet. We line up included and excluded items on that packet; we do not claim a press or a market cut.
