 Quality Acceptance Criteria

According to customer's requirements


Q1: What is the normal lead time for product orders?

A: Average lead time for prototype / first article is 1-2 weeks; if tooling is involved, lead time for production tooling is 10-15 days; average production time after sample approval is 2-3 weeks.

Q2: What is your standard packing?

A: All the goods will be packed by carton box and loaded with pallets. Special packing method can be accepted when needed.


Q3: Could you please tell us the month capacity of your products?

A: It depends on which model, we produce more than 3000 tons rubber materials per month.

Q4: What kind of certificates you have?

A: We have obtained ISO9001:2008 and ISO / TS 16949:2009.

Q5: How to check the quality of the bulk order?

A: We provide pre-production samples before mass production for all customers if needed.  Quality certs can be provided, such as measurement report, material data sheet, COO, COA … before delivery. Third party inspection is accepted such as SGS, TUV, INTERTEK, BV, etc.


Q6: How to select the raw compound for my application?

A: With years of experience working with a variety of material, we can help select the material that will best suit your needs while keeping material costs in mind.


Q7: Do you use any international standards for the rubber products?

A: Yes, we mainly use ASTM D2000 standard to define the quality of the rubber materials, tolerances as per ISO3302, ISO2768, etc.

Q8: Can you supply different color materials?

A: Yes, we can produce custom molded rubber and silicone rubber products in different colors, the color code will be required in case of an order.


Q9: What materials are available to produce from your side?

A: NBR, EPDM, SILICONE, VITON (FKM), NEOPRENE (CR), NR, IIR, SBR, ACM, AEM, Fluorosilicone (FVMQ), FFKM, Liquid Silicone, Sponge, etc.

Q10: What other services does NJK Rubber offer?

A: NJK Rubber has in-house tooling capabilities for molds; we have our own lab for material testing; we have a Cold Room used for elastomer storage to prolong product life.

Q11: What is the life expectancy of the rubber seal?

A: Product life is contingent upon many factors, including environment, cycles, pressure, etc. NJK Rubber cannot predict seal life under all the varying conditions of operation. Accelerated life testing may be performed by customer to determine expected life, but must be conducted in dynamic application.
