Question 1

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 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 5

How does RESRUB control product quality?

Accepted Answer

Quality is checked at every production stage.

Every batch starts with raw-material verification, follows documented extrusion and curing parameters, and ends with dimensional and visual final inspection. We keep inspection records so issues can be traced back to a specific machine, batch and operator if needed.

In-house testing laboratory

Our lab performs physical tests (tensile strength, elongation, hardness, tear, abrasion), chemical aging (heat aging, ozone, acid/alkali) and mechanical life tests. This lets us validate compounds quickly instead of waiting for third-party results.

Process control and documentation

Key dimensions are checked at setup and at intervals during production. We use SPC on critical dimensions, and every order gets a final inspection report based on the agreed AQL. Certificates of conformance and test reports can be provided on request.

Next step: Ask us for sample inspection reports or visit our laboratory virtually.

Question 6

What quality certifications does RESRUB hold?

Accepted Answer

We maintain a full automotive-grade quality system.

Our factory in Dongguan, China operates under IATF 16949:2016, ISO 9001:2015 and ISO 14001:2015. We also offer REACH and RoHS-compliant material options for European and North American markets.

What each certification means for buyers

IATF 16949 is the global automotive quality standard; it means our processes are controlled for traceability, defect prevention and continuous improvement. ISO 9001 covers general quality management, and ISO 14001 verifies our environmental management. REACH/RoHS compliance ensures materials meet restricted-substance limits for the EU and similar regions.

Audited automotive supply history

Our quality system has supported projects for BYD, Changan, Changan Ford and Yutong bus. This audit history gives tier-1 and export buyers confidence that our documentation, inspection records and process controls meet strict customer requirements.

Question 7

What is the difference between solid and sponge rubber profiles?

Accepted Answer

Solid profiles carry load; sponge profiles seal with less force.

Both solid and sponge (foam) rubber profiles are extruded on the same production lines, but the compound and curing process are adjusted to give very different mechanical properties. Choosing the right type depends on your sealing gap, closure force and environmental exposure.

Solid rubber profiles

Dense, durable and strong. Solid profiles are used where the seal must support weight, resist cutting or maintain a precise shape. Typical applications include anti-collision strips, heavy-duty gaskets and wear pads.

Sponge / foam rubber profiles

Closed-cell or open-cell sponge is much lighter and compresses easily. It is ideal for door seals, enclosure gaskets and appliance seals where a small closing force must fill an uneven gap. We can control density, hardness and cell structure to match your water, dust or noise requirements.

Next step: Send us your gap dimensions and compression requirements and we will recommend the right profile type.

Question 8

Do you produce braided and reinforced rubber hoses?

Accepted Answer

Yes — braiding and reinforcement are core capabilities.

We produce braided rubber hoses and middle-layer-fiber-reinforced hoses for applications that need extra pressure retention, flexibility and abrasion protection. Our braiding workshop covers polyester, polypropylene and other composite reinforcements.

When to choose braided or reinforced hose

Choose braided hose when the tube is exposed to movement, vibration or external wear. Choose middle-fiber-reinforced hose for higher internal pressure or when the hose must keep its shape under load. Our engineering team can match the reinforcement type and braid density to your pressure and bend-radius specs.

Sizes and end fittings

Common inner diameters range from 3mm to 50mm, with wall thickness, length and color customizable. We can also support OEM assemblies with molded fittings, clamps and quick-connects upon request.

Question 9

Can you supply liquid-cooling rubber hoses for PC and AI servers?

Accepted Answer

Yes — we specialize in low-evaporation cooling hoses.

Our PC and AI-server liquid-cooling hoses are designed to handle glycol-water mixtures, long-term heat cycles and tight bend radii inside compact chassis. We target an evaporation rate as low as 0.2% on our premium PC liquid-cooling grade.

Reinforcement options

Depending on pressure and abrasion needs, we supply plain extruded tubes, middle-fiber-reinforced tubes and polyester-braided outer layers. Our 2024-added weaving workshop has 10 automatic braiding machines dedicated to liquid-cooling and reinforced hose production.

Typical sizes and customization

Inner diameters commonly range from 6mm to 25mm, but we can extrude custom IDs/ODs and wall thicknesses. Colors, lengths, cut-to-length pieces and custom fittings are all available, with MOQ as low as 1 piece for prototyping.

Next step: Learn more about our liquid-cooling solutions for gaming PCs and AI servers.

Question 10

What rubber materials can RESRUB extrude?

Accepted Answer

We extrude a wide range of rubber and plastic elastomers.

Our factory works with EPDM, silicone, NBR, CR, IIR, SBR, FKM, PVC, TPE/TPR/TPV and TPU. This lets us match material to temperature, chemical exposure, hardness, color and cost requirements rather than forcing a one-size-fits-all choice.

Common materials and their best uses

EPDM is the workhorse for outdoor hoses, seals and coolant lines because of its water, ozone and UV resistance. Silicone handles extreme temperatures (-60°C to 200°C+) and is ideal for food-contact or medical tubing. NBR offers excellent oil and fuel resistance. PVC and TPE/TPR/TPV provide lower-cost, recyclable options for appliance seals and grips. FKM is used when aggressive chemicals or very high heat are involved.

Material selection support

If you are unsure which polymer fits your product, send us your drawing, target application and operating conditions. Our engineers can recommend the right compound, hardness (Shore A 20–90) and color, and we can produce small test samples for validation before volume production.

Next step: Need help choosing a material? Send your specs and we will recommend the best compound.
