Gainer’s FOB range of $9-18 covers most corded and entry-level cordless configurations. Accessories (whisk, chopper bowl, measuring cup) add $1.50-2.50 to the ex-factory cost.
Quality Control: Beyond the Checklist
A factory producing 250,000+ units monthly cannot rely on final inspection alone. Gainer’s QC architecture:
– IQC (Incoming Quality Control): Every batch of plastic resin is tested for Melt Flow Index. Steel for shafts is checked with XRF for composition. Battery cells are tested for internal resistance and capacity on a sample basis.
– IPQC (In-Process Quality Control): At each station — motor assembly, PCB soldering, housing assembly — operators perform self-inspection, and QC inspectors do random checks at 2-hour intervals.
– FQC (Final Quality Control): Every unit runs a 30-second function test (start, speed change, stop, abnormal noise check). 100% of units on the production line. AQL 2.5 sampling for cosmetic defects.
– OQC (Outgoing Quality Control): Pre-shipment inspection against ANSI/ASQ Z1.4, Level II, AQL 2.5/4.0.
FAQ
Q: What’s the difference between ODM and OEM for immersion blenders?
A: OEM means you provide the design; the factory builds it. ODM means the factory provides a pre-engineered platform that you can customize with your brand’s housing design, color, accessories, and packaging. ODM is faster (8-12 weeks vs 12-16 weeks) and has lower upfront R&D costs.
Q: Can I modify an ODM immersion blender’s motor specifications?
A: Yes, within the platform’s constraints. Gainer’s BLDC platform can be tuned for different RPM ranges (8,000-15,000) and power levels (150-250W) through firmware changes. Radical changes (different motor size) require a new platform.
Q: Does Gainer hold the certifications for its ODM platforms?
A: Yes. Existing platforms carry CE, GS, CB, RoHS, LFGB, and ETL certifications. Customized versions typically need only delta testing rather than full certification, saving 3-4 weeks and $3,000-5,000.
Q: What’s the typical MOQ for ODM immersion blenders?
A: 1,000-2,000 units per model. Lower than OEM because the molds already exist. Payment terms: 30% T/T deposit, 70% balance before shipment.
Q: How does Gainer protect ODM customer designs from being copied?
A: The 77+ patents cover the core mechanical designs. NDA is standard. Customer-specific molds and color formulations are exclusive to that customer. Gainer has served Tristar, Scarlett, Redmond, and Vitek, all of whom operate with design exclusivity agreements.

The ODM Engineering Team
Behind Gainer’s ODM platforms is an engineering team that handles the transition from concept to production. The team structure:
– Industrial Design (3 designers): Produce 3D renderings and CMF definitions. Use SolidWorks for CAD, Keyshot for rendering. Average 5 years of appliance design experience.
– Mechanical Engineering (5 engineers): Handle motor integration, gear train design, housing structure, and mold flow analysis. Use Moldflow for injection molding simulation.
– Electrical Engineering (3 engineers): Handle BLDC motor controller design, PCB layout, battery management, and EMC compliance. Use Altium Designer for PCB design.
– Certification Engineering (2 engineers): Manage the certification process, prepare Technical Files, coordinate with TÜV and SGS, and handle delta testing.
– Project Management (3 managers): Coordinate between the customer and the engineering team, manage timelines, and provide weekly updates. Related: Cordless Hand Blender OEM.
This 16-person team is the reason Gainer can deliver ODM products in 8-12 weeks. The team has done it before — the platforms are proven, the certification process is familiar, and the supply chain is established. This connects to our guide on Hand Blender with CE GS Certification.
Material Selection for Food Contact
Every material that touches food in an immersion blender must be food-safe. Gainer’s material selection process:
– 304 stainless steel (1.4301): The standard for blending shafts and blades. Austenitic structure (non-magnetic), 18% chromium, 8% nickel. Resistant to corrosion from acidic foods (tomatoes, citrus). LFGB and FDA compliant.
– 420J2 stainless steel: Used for blades where hardness is needed. Martensitic structure, 0.3% carbon. Hardened to HRC 52-55. The carbon content makes it slightly less corrosion-resistant than 304, but the blade is in constant motion and doesn’t hold food — so corrosion is not an issue.
– PP (Polypropylene): Used for chopper bowls, measuring cups, and splash guards. BPA-free. LFGB and FDA compliant.
– Silicone rubber: Used for seals and gaskets. Food-grade (platinum-cured, not peroxide-cured). LFGB and FDA compliant.
– POM (Polyoxymethylene): Used for gear components in the chopper attachment. Self-lubricating, food-grade (low formaldehyde migration). LFGB compliant. For more, read Stick Blender Contract Manufacturing.
Gainer’s material suppliers are qualified through the ISO 9001 supplier evaluation process. Each batch of food-contact material is tested for heavy metal migration and overall migration per LFGB requirements. We explore this further in Best Kitchen Appliance OEM Manufacturers Shenzhen.
The Competitive Landscape
The immersion blender ODM market in Shenzhen has a few dozen factories. What separates the top tier from the rest:
– In-house BLDC motor production: Most factories buy motors from third-party suppliers. Gainer’s in-house motor line means control over quality, cost, and innovation.
– Patent portfolio: 77+ patents signal ongoing R&D investment. Most factories have zero patents.
– Certification depth: CE is common. CE + GS + CB + ETL + LFGB + FDA + SAA is rare. Gainer has all of them.
– Client references: Tristar, Scarlett, Redmond, Vitek. These are European consumer brands, not obscure trading companies.
– BSCI certification: Most Shenzhen factories don’t have BSCI. European retailers require it. See also: Hand Blender OEM Manufacturer.
A factory with all five traits is rare. Gainer is one of them.
