Rubber Molded Service Custom Rubber Seal
Custom Molded Rubber Seals — Drawing, Tooling and Sample Approval
Rubber seal molding from specified geometry to sample review
Send the seal drawing, mating-part dimensions, compound requirements and annual quantity. Compression or injection molding is selected against the geometry and production requirements; a custom seal needs agreed dimensions, flash limits and acceptance criteria before tooling is confirmed.

Our company
Shanghai Qinuo Industry Co. Ltd
provides molded rubber seal and related plastic component enquiries for industrial equipment.
For a custom seal, specify the sealing surface, assembly squeeze, dimensional tolerances and permitted parting-line or flash locations.
Tooling and inspection requirements are reviewed for the selected compound and geometry. Include any metal insert, bonding, marking or surface-finish requirements.
ISO 9001 quality management is available. Product-specific material, regulatory and test documentation is agreed for the requested compound and application.
The steps of the production:
FAQ
1. What is needed to develop a custom molded seal?
Provide a dimensioned drawing and revision, mating hardware geometry, sealing direction and assembly conditions. A sample can support profile identification but should be accompanied by measured dimensions and requirements.
State whether the component is a static gasket, dynamic seal or non-sealing molded part; each needs different acceptance criteria.
2. How is the rubber compound selected?
a. Specify the exact fluid and additives.
b. Include normal and peak operating temperatures.
c. State nominal Shore A hardness and tolerance.
d. Include pressure cycles, motion and operating clearance where relevant.
e. Specify compression-set, tensile or tear requirements when needed.
f. Confirm color separately from material identity.
g. Density and chemical resistance are properties of the specified formulation, not universal values for every rubber seal.
3. What should be checked on molded samples?
1. Critical dimensions and tolerances against the drawing revision.
2. Sealing surfaces, flash and parting-line placement.
3. Compound identity and hardness requirements.
4. Fit with the actual mating parts and installation method.
5. Agreed functional tests under the specified service conditions.
4. What determines tooling and delivery?
1. Part geometry, mold construction and cavity arrangement.
2. Selected compound and manufacturing process.
3. Sample review, inspection requirements and quantity.
4. Marking, packing and documentation requirements.
5. Confirm the schedule after the drawing and sample requirements are agreed.
Custom rubber seal enquiries: provide the drawing, mating geometry, compound and sample acceptance requirements.
Send your design drawing or original sample with critical dimensions and application details.
