Our custom compounds run in production lines across five core manufacturing sectors — each backed by proven, field-validated grades.
Housings and internal parts for air conditioners, washing machines and small appliances — flame retardant, heat resistant and color-stable.
Recommended grades: FR PC/ABS · FR-PP
Drill and grinder housings that survive drop tests and job-site abuse — high rigidity, impact resistant and flame retardant.
Recommended grades: PA6-GF30 · FR PC/ABS
Under-hood and structural components with long-term heat resistance, mechanical strength and dimensional stability.
Recommended grades: PA66-GF30
Connectors, switchgear and EV charging components — UL94 V-0 flame retardancy with CTI and glow-wire compliance.
Recommended grades: PA66-FR · FR PC/ABS
Chair mechanisms, casters and structural parts — toughness and fatigue resistance for years of daily use.
Recommended grades: PA6-GF30 · PA6-40GF
Three real custom projects — formulations developed by Jinsu engineers, photos of actual production parts
Under continuous dry friction the original material wore quickly and ran noisy. Custom lubricated PA66 lowered the friction coefficient to 0.15–0.25 (typical) with self-lubrication, no external grease needed.
Significantly longer wear life and quieter running — now in stable mass production replacing the original material
Clip-style structural parts must survive repeated assembly without cracking. Custom toughened glass-fiber system balances stiffness and ductility: notched impact typically ≥15 kJ/m², no cracking in low-temperature drop tests.
Passed repeated insertion-removal validation, replacing an imported grade with domestic sourcing
Metal housings are heavy and create electrical safety risks. Custom thermally conductive insulating PA6 with 1.0–2.0 W/m·K replaces metal in a single injection-molded part.
Lighter luminaire, eliminated conductivity risk, thermal management meets long-life design targets
Jinsu operates professional compounding lines capable of customizing various modified plastic pellets:
From raw material to finished pellets, every step is precisely weighed, mixed, extruded and inspected.
A standard custom project completes in 4–6 weeks, with clear deliverables at every stage
Confirm operating conditions (temperature, load, safety standards, regulations); match an existing grade or start a custom formulation
Formulation design and lab-scale compounding; free 5–10 kg samples with a preliminary TDS
Injection trials verify flow, shrinkage and appearance; formulation iterated if needed
25–500 kg pilot batch for in-assembly validation; formulation and process window locked
Production scheduled with COA and retained samples per batch, shipped FOB Shanghai/Ningbo
Real shots from our Suzhou factory — custom and volume orders run on the same managed lines for reliable lead times
From first inquiry to mass production — transparent terms, no surprises.
5–10 kg free sample for testing; you only cover freight. Dispatched within 1–3 working days.
Standard grades from 25 kg (one bag). Custom compounds typically 100–500 kg depending on formulation complexity.
Stock grades: 1–3 working days. Custom compounds: 7–15 working days depending on formulation and quantity.
Send us your sample, specification or a competitor's product — our engineers develop the recipe with you.

FOB, CIF, EXW supported. Sea, air and rail freight; T/T and L/C payment accepted.
Custom compounding is priced per project. Four factors drive your quotation — our engineers explain each one before you commit.
PA6 is more economical than PA66; PC and alloys sit higher. Choosing the lightest resin that meets your spec is the biggest cost lever — we help you avoid over-specifying.
Glass fiber, flame retardants (halogen-free systems cost more than halogenated), tougheners, UV stabilizers and conductive fillers each add to recipe cost in proportion to loading.
Larger batches spread fixed compounding and lab-verification costs over more kilograms. Annual contracts unlock better resin pricing from our bulk procurement.
Standard black or natural adds no extra cost; Pantone color matching, food-contact or special certifications add sampling and testing steps.

Your target application, preferred base resin (or let us recommend one), required mechanical, thermal or flame-retardancy specifications, color, and estimated annual volume. A drawing or photo of the part also helps. Our engineers reply with a formulation proposal and quotation within 24 hours.
Yes. Send us a physical sample or a competitor's datasheet; our laboratory analyzes it with TGA, XRF and FTIR to identify the base resin and additive system, then reproduces or improves the formulation. You receive complete test data for approval before mass production.
Standard modified grades start from 25 kg (one bag). Fully custom formulations typically start at 100–500 kg depending on formulation complexity and raw material MOQ. For new projects we recommend starting with a 5–10 kg free sample trial.
Samples of standard grades are dispatched within 1–3 working days. Custom developments usually take 7–15 working days including formulation design, compounding and laboratory verification. After your approval, mass production is backed by 3,000+ tons of monthly capacity.
Yes. We match Pantone/RAL codes or your physical color sample with a spectrophotometer, achieving ΔE ≤ 1.0. Color masterbatch is dosed gravimetrically on-line for batch-to-batch color consistency.
PA6 and PA66 are our core specialty, and we also compound PC, PC/ABS, ABS, PP and engineering alloys — with glass fiber reinforcement, flame retardancy, toughening, conductive, UV-stable and wear-resistant modifications. Browse our product range for available grades.
Every batch ships with a COA. A complete TDS is provided for each grade, and SGS or other third-party test reports are available on request. Our quality system is ISO 9001:2015 certified.
Yes. Send us a sample or the TDS/datasheet and we run a formulation analysis with benchmark sampling — replacement samples typically ship in 5–7 days. Alternatives meet RoHS/REACH requirements, and third-party test reports can be arranged on request.
Existing grades start at 25 kg. Production MOQ for custom colors and formulations is typically 500 kg–1 ton; sampling and pilot batches can be as low as 25 kg, confirmed during project review.
Formulation and process parameters are locked after approval and never changed unilaterally. Every batch ships with a COA, key properties are 100% tested, and retained samples are kept for two years for full traceability.
We adjust the formulation and re-sample for free until your validation passes — each sampling round takes 5–7 days. Mold-trial related costs are negotiated per project.
A standard project runs 4–6 weeks from inquiry to first delivery: requirement review 1–2 days → formulation sampling 5–7 days → mold trial 7–10 days → pilot batch 5–7 days → mass production shipment 10–15 days. Rush projects can be compressed to around 3 weeks by running stages in parallel.
