Clipper Blade Manufacturing Process
MIM Injection
Metal + Binder → Green Part
Fine metal powder mixed with polymer binder, injected into precision molds. Complex tooth geometries formed in a single shot. ±0.02mm tooth pitch accuracy.
Debinding & Sintering
1200–1350°C Vacuum Furnace
Binder removed, metal particles fused at high temperature. Parts achieve 97–99% theoretical density. Controlled atmosphere prevents oxidation.
Heat Treatment
HRC 58–62 Hardness
Quenching and tempering to achieve optimal blade hardness. Precise temperature control ensures consistent cutting edge retention across production batches.
CNC Grinding & Lapping
Ra 0.4–0.8μm Surface
Precision flat grinding and lapping for blade mating surfaces. Critical for blade-to-blade contact that determines cutting performance.
Surface Coating
Ceramic / Titanium / DLC
Optional performance coatings: ceramic (stays cool), titanium nitride (gold, wear-resistant), DLC (ultra-hard, low friction). Extends blade life 2–5×.
Assembly & Testing
100% Cut Test
Blade pairs assembled with spring tension set to spec. Every blade set undergoes cut testing on test media before packaging.
Clipper Blade FAQ
What clipper blade types does SUMTHIN manufacture?
SUMTHIN manufactures a complete range of professional and consumer clipper blades: detachable blades (A5-type universal fit), adjustable taper blades, T-blade/trimmer blades, ceramic-coated blades, titanium-coated blades, and replacement blade sets. We also produce precision metal components for pet grooming clippers, barber trimmers, and body groomers. Materials include high-carbon stainless steel (440C), ceramic, and proprietary MIM alloys.
What is Metal Injection Molding (MIM) and why use it for blades?
Metal Injection Molding (MIM) combines the design flexibility of plastic injection molding with the material properties of powder metallurgy. For clipper blades, MIM produces: complex tooth geometries impossible with traditional stamping, consistent tooth pitch accuracy (±0.02mm), superior surface finish (Ra 0.4–0.8μm), high hardness after sintering and heat treatment (HRC 58–62), and net-shape parts requiring minimal secondary machining. SUMTHIN has 20+ years of MIM expertise with dedicated sintering furnaces and heat treatment lines.
What is the daily production capacity?
Our factory produces 250,000+ clipper blades per day across multiple production lines. The 40,000m² facility houses: MIM injection lines, sintering furnaces, heat treatment, CNC grinding, lapping, coating (ceramic/titanium/DLC), and assembly lines. With 360+ employees operating in shifts, we can scale production to meet seasonal demand peaks.
What is the MOQ for OEM clipper blades?
MOQ depends on blade type: Standard blade models (existing tooling): 5,000 pieces. Custom blade geometry (new MIM tool): 20,000+ pieces. Custom coating (ceramic/titanium): 10,000+ pieces. Private label packaging: 5,000+ pieces. Tooling cost for new blade designs: $8,000–$25,000 depending on complexity. Prototype samples: 50–100 pieces for validation before mass production.
Which brands does SUMTHIN OEM for?
We are the OEM manufacturing partner for several leading professional clipper and grooming brands worldwide. Due to NDA agreements, we cannot name specific brands publicly. However, our blades are found in professional barbershop clippers, consumer grooming devices, and pet grooming tools sold globally. We welcome factory audits and can provide customer references upon signing NDA.
