Question 1

Do you keep stock moulds and semi-finished stock for faster delivery?

Accepted Answer

Common dies and semi-finished stock cut weeks off the first order.

A new mould is only needed when the cross-section is new. For the sizes that repeat across orders, we keep the die in the tool room and hold semi-finished extrudate that can be cut to your length, inspected and packed without waiting for a full production slot.

What is kept in stock

Common dies: 7x4, 8x4, 10x6 and 5x3 mm sections are the sizes ordered most often and stay in the tool room.
Semi-finished stock: common bore sizes around 6, 8 and 10 mm, ready to cut to length.
New tooling: 1 to 3 days, from RMB 500 depending on section complexity.

Where a new die is still the better route

If your section differs only slightly from a stock die, we will say so: reusing the die and adjusting the compound is usually cheaper and faster than cutting a new one. When a new die is needed, we quote the tooling cost separately and confirm the sample before mass production.

Next step: Send your section drawing and we will tell you whether a stock die fits.

Question 2

How fast can you make samples and tooling?

Accepted Answer

Fast tooling and sampling are built into our process.

We keep our tool room and prototype extrusion line ready for quick-turn samples. For straightforward profiles, we can cut tooling and produce samples within 24 hours of confirming the drawing. Complex multi-layer hoses or braided assemblies may take a few days, but we always aim to compress the development cycle.

Typical sample lead times

Simple solid profiles and tubes: same-day or 24 hours after drawing confirmation. Sealing strips with adhesive backing or custom cross-sections: 1–3 days. Braided or reinforced hoses: 3–7 days depending on braid density and fitting requirements.

No-cost design support

We provide free design assistance and compound recommendations based on your application. You do not pay for mold design advice, and our MOQ for prototype orders is just 1 piece so you can validate fit, function and appearance before committing to volume.

Next step: Send your drawing now and we will confirm sample timing within one business day.

Question 3

Do you support OEM/ODM and private labeling?

Accepted Answer

Yes — OEM, ODM and private-label projects are welcome.

We act as a manufacturing partner for brands, distributors and equipment manufacturers. You provide the brand, package design and product spec; we handle tooling, production, quality control and shipment under your label.

What we can put your brand on

Products can be printed with your logo or part number during extrusion or by post-processing. Packaging can use neutral boxes, your branded cartons, barcode labels, instruction sheets and pallet markings. We can also prepare certificates and test reports under your brand name.

ODM design service

If you only have a function requirement, our team can design the cross-section, choose the compound and produce prototypes for validation. We protect your design under NDA and do not sell your private molds to other customers.

Next step: Start an OEM/ODM discussion with our sales team.

Question 4

What customization options do you offer?

Accepted Answer

Almost every property of the product can be customized.

We design and extrude rubber hoses, seals and profiles around your requirements. You can provide a 2D/3D drawing, a physical sample, photos or a written spec. Our engineers turn it into a production-ready tool and sample, often within 24 hours for simple profiles.

Rubber profile cross-sections

Logo printing on profiles

Customizable parameters

Material: EPDM, silicone, NBR, PVC, TPE/TPR/TPV, FKM and more. Color: matched to Pantone or RAL codes. Hardness: Shore A 20–90. Geometry: any cross-section we can tool, including hollow, bubble, lip, locking groove and multi-cavity profiles. Surface: smooth, textured, printed logo/part number, or pressure-sensitive adhesive backing.

Low minimums for validation

MOQ starts at 1 piece for prototypes and small trial orders. Once the design is approved, we can scale to volume production on our five large extrusion lines, with a daily output of 3–5 tons of compound and an annual extrusion capacity of 60 million metres.

Question 5

Can you produce custom rubber hoses and sealing strips according to our drawings or samples?

Accepted Answer

Yes — RESRUB manufactures fully custom rubber hoses and sealing strips to your drawings or samples.

Send us a 2D technical drawing, 3D CAD file (STEP / IGES / STL), a physical sample, or a written specification. Our engineering team will confirm the material, dimensions, hardness, color and performance targets, then build a prototype for your approval before mass production. We support both OEM (build to your print) and ODM (design suggestions and improvements) workflows for global B2B buyers.

Things to know before you order

Tolerance: Standard ±0.5 mm on extruded dimensions. Tighter requirements are reviewed case by case during engineering review.
Tooling: Standard sizes (round, square, D-shape) usually need no new die. Custom irregular profiles need a one-time tooling fee (refundable or amortised over order volume).
MOQ: Hoses 500 m, sealing strips 1,000 m for mass production. Sample orders below MOQ are negotiable for first-time cooperation.
Color & hardness confirmation: For new custom colors we recommend a small trial batch first to confirm the shade before bulk run.
