FAQ
Q: Are your sink flanges OEM or aftermarket replacements?
A: This product is an independently manufactured aftermarket replacement part; it is not an official Insinkerator OEM accessory.
It is designed based on standard Insinkerator mounting structures and is suitable for the aftermarket and wholesale channels.
Q: Is it fully compatible with all Insinkerator models?
A: The product fits standard Insinkerator three-point locking and Quick-Lock systems, though dimensions vary by model.
We generally recommend:
Providing a sample of the old part or a dimension drawing
Or verifying the specific model for compatibility
Q: What is the Minimum Order Quantity (MOQ)?
A: Standard MOQ is typically:
500 – 2,000 pcs (depending on the model and customization requirements)
For new mold development: The MOQ may be slightly higher to amortize tooling costs.
Q: Can samples be provided? How long does it take?
A: Samples are available:
Standard designs: 7–10 days
Designs requiring new molds: 15–20 days
Samples are typically used for:
Installation testing
Customer channel verification
Pre-listing confirmation for Amazon
Q: Do the materials meet export standards?
A: Yes, standard materials include:
SUS304 / SUS316 stainless steel
Compliant with ASTM A240 material standards (MTC material certificates provided upon request)
Optional upgrades:
Higher corrosion resistance grade (316)
Surface passivation treatment
Q: Is the product prone to rusting?
A: The product offers excellent corrosion resistance in typical kitchen environments (exposed to moisture and grease).
Key factors affecting longevity include:
Material grade (304 vs. 316)
Surface treatment method
Environmental humidity and cleaning frequency
Under standard usage conditions, premature rusting will not occur.
Q: How do you ensure batch consistency?
A: We ensure stability through a tiered quality control system:
IQC: Raw material inspection (thickness + material composition)
FAI: First Article Inspection (dimensional verification)
IPQC: In-process spot checks
OQC: Outgoing inspection + assembly spot checks
Q: Is OEM branding/customization available? We support OEM/ODM customization, including:
A: Laser-engraved logos
Molded brand markings
Customized individual packaging designs (for retail or wholesale)
Q: What is the typical lead time?
A: Standard order lead times:
Standard products: 20–30 days
Customized products: 30–45 days (including mold development)
Actual lead times depend on:
Order quantity
Whether mold creation is required
Surface finish specifications
Q: What happens if there is a dimensional mismatch?
A: We recommend the following steps prior to placing an order:
Sample confirmation
Providing a sample of the existing part for matching and development
