Our dedicated facility in Tongqin Town, Zhejiang provides comprehensive capacity for volume production, material warehousing, and rapid export logistics.
Office & Showroom
Equipped with modern engineering offices and an extensive sample showroom displaying hundreds of private-label coffee grinders and spice mills.
Production Workshop
Structured manufacturing zones following strict 6S workshop management principles, ensuring high operational efficiency and inline worker safety.
10 In-House Production Lines
Total vertical integration across all key processes guarantees fine dimensional control, consistent surface finishes, and on-time order fulfillment without subcontracting dependencies.
Line 01 Raw Material
Food-grade polymer resins, stainless steel coils, and premium ceramic grinding cores undergo strict incoming lot verification.
Line 02 Injection Molding Line
High-tonnage injection units produce burr housings, gear teeth, buttons, and custom exterior shells with tight tolerances.
Line 03 Cutting Line
Automated cutting machinery slices stainless steel tubes and rods cleanly to exact engineered product dimensions.
Line 04 Punching Line
Multi-stage stamping presses form internal structural brackets, contact plates, and decorative metallic sleeves.
Line 05 Laser Cutting Line
High-precision laser processing for burr-free window openings, ports, and intricate cylindrical contours.
Line 06 Hydraulic Bulging Line
Specialized hydraulic fluid expansion creates ergonomic curved profiles on stainless steel mill housings with zero weld lines.
Line 07 Polishing Line
Multi-step brushing and mirror polishing stations deliver scratch-free satin, brushed, or reflective finishes.
Line 08 Inspection Line
Every sub-assembly is screened for motor torque, alignment, cosmetic perfection, and button actuation prior to casing.
Line 09 Assembly Line
Skilled operators pair motors, burrs, drive shafts, and PCB control modules on antistatic continuous conveyor benches.
Line 10 Packing Line
Automated bagging, custom retail gift box packing, barcode verification, and export carton strapping for sea and air freight.
Core Manufacturing Machinery
Our heavy capital investments in dedicated machinery ensure micro-precision forming, smooth operation, and batch-to-batch consistency across orders.
Injection Molding Machine
Precision micro-controlled injection machines providing stable thermal profiles and uniform wall thickness.
Cutting Machine
Heavy-duty circular and pneumatic cold saws providing smooth end cuts without heat deformation.
Punching Machine
Automated punch presses performing rapid shearing, stamping, and hole punching with progressive dies.
Laser Tube Cutter
3D CNC rotary fiber laser cutter designed for high-speed, intricate slots, viewing windows, and cutouts.
Hydraulic Machine
High-tonnage hydraulic presses utilized for deep drawing, hydro-bulging, and high-impact structural shaping.
In-House Testing & Reliability Laboratory
Kitchen grinders and salt mills must resist harsh corrosive seasonings, high humidity, repeated motor torque, and drops. Every model is validated inside our on-site laboratory.
Salt Spraying Chamber
Simulates corrosive conditions to evaluate oxidation resistance on all stainless steel housings, screws, and metal grinding cores.
Temp & Humidity Chamber
Stresses plastic housings, adhesive seals, and electronic assemblies under cyclical extreme climatic variations.
Battery Testing Machine
Evaluates lithium-ion cell capacity, charging cycles, internal resistance, and over-current protection thresholds.
Bursting Strength Tester
Measures corrugated fiberboard burst resistance to guarantee shipping packaging withstands long-haul ocean container transit.
Voltage Endurance Tester
Validates high-voltage breakdown resistance and electrical insulation safety in accordance with CE and CB safety directives.
IQC Incoming Inspection
Dimensional, chemical, and hardness inspection of all incoming stainless steel coils, plastic granulates, and ceramic burr cores before entering lines.
IPQC In-Process Monitoring
Continuous sampling checks on injection accuracy, laser cutting margins, torque tolerances, and electrical wiring assembly at every step.
FQC Pre-Shipment Audit
100% functional live test, aesthetic check, drop simulation, and packaging audit following international AQL 1.5/4.0 standards.
