Aluminum Alloy CNC Hardware Parts Casing Custom Parts Machining Services
Aluminum alloy coffee machine accessory casing, custom-made with CNC numerical control processing
The core principles for selecting materials for coffee machine hardware parts are food contact safety, high temperature & pressure resistance, corrosion resistance, easy cleaning, and machining compatibility. Machining pitfalls mainly focus on preventing deformation & oxidation, controlling precision, avoiding contamination, and ensuring sealing.
Material Selection for Coffee Machine Hardware Parts
Core Food-Contact Components
(Boilers, Brew Heads, Portafilter Baskets, Water Circuit Joints, Valves)
First Choice: Food-grade Stainless Steel (304/316L)
  • Advantages: Compliant with GB 4806.9-2023 national food contact standards, no heavy metal migration; resistant to corrosion from hot water, steam and coffee liquid, rust-proof, no patina formation, high structural strength, deformation resistance, easy cleaning and long service life.
  • Application: Boilers, brew heads, portafilter baskets, high-pressure joints, steam pipe connectors, filter screens, etc.
  • Grade Selection: 304 offers cost-effectiveness, suitable for both household and commercial coffee machines; 316L provides better resistance to chloride ions (adaptable to poor water quality & cleaning agents), preferred for high-end commercial equipment.
Second Choice: Brass (H59/H62, with food-grade plating)
  • Advantages: Excellent thermal conductivity & stable temperature control (ideal for boilers/brew heads); superior machinability for precise thread processing and reliable sealing; uniform thermal expansion & contraction to resist stress cracking.
  • Risks: Prone to patina and heavy metal precipitation; must be treated with food-grade nickel/chromium plating or passivation, with plating temperature resistance ≥150℃ and anti-peeling durability.
  • Application: Small & medium-sized boilers, water circuit joints, valves, handle bases (non-direct coffee liquid contact parts).
Forbidden/Not Recommended: Ordinary carbon steel & iron (easy rusting, coffee contamination); non-food-grade unplated copper alloys.
Structural/Shell/Non-Contact Parts
(Brackets, Outer Casings, Handles, Knobs, Bases)
First Choice: Aluminum Alloy (6061/5052, anodized)
  • Advantages: Lightweight, good thermal conductivity, easy die-casting/CNC machining, cost-controllable; anodized surface features wear resistance, corrosion resistance, easy cleaning and premium appearance.
  • Application: Outer casings, brackets, handles, knobs, non-pressure-bearing structural parts.
Alternative: 304 Stainless Steel
  • Advantages: High-end texture, durability and easy cleaning; suitable for outer casings & decorative parts of high-end models.
Sealing/Wear-Resistant Auxiliary Parts
(Valve Cores, Valve Seats, Gaskets, Bearings)
  • PTFE (Teflon): High temperature resistance (-200~260℃), chemical inertness, low friction and odor-free, used for high-temperature sealing & valve cores.
  • Ceramics: Wear-resistant, corrosion-resistant and metal-contamination-free, applied for grinding discs and valve cores.
  • Food-grade Silicone/EPDM: Used for O-rings and gaskets, featuring temperature resistance, aging resistance and excellent sealing performance.
General Principles of Material Selection
  • Direct contact with coffee/hot water/steam: Food-grade 304/316L stainless steel > Food-grade plated brass
  • Non-contact structural/shell parts: Anodized aluminum alloy > Stainless steel
  • Sealing/wear-resistant parts: PTFE/Ceramics > Food-grade rubber
Machining Pitfall Avoidance
CNC Machining (Stainless Steel/Brass/Aluminum Alloy)
Machining Pitfalls of 304/316 Stainless Steel
Pitfall 1: Severe work hardening, tool sticking & rapid tool wear
Causes: High toughness & poor thermal conductivity of stainless steel, concentrated cutting heat and hardened layer formation.
Solutions:
  • Tools: Cobalt-containing high-speed steel / coated carbide tools (TiCN/AlTiN) for sharpness and wear resistance.
  • Parameters: Low rotating speed, moderate feed rate, large cutting depth, one-time forming to avoid secondary cutting hardening.
  • Cooling: High-pressure sufficient extreme-pressure cutting fluid for forced cooling and chip removal.
Pitfall 2: Deformation of thin-walled/slender parts
Causes: Clamping force, cutting force and internal stress-induced deformation.
Solutions: Special tooling (soft jaws/vacuum fixtures), step-by-step cutting, stress relief annealing (300~400℃ heat preservation) and post-machining aging treatment.
Pitfall 3: Surface scratches & oxidation
Solutions: Special cutting fluid, timely cleaning, passivation/electropolishing to enhance corrosion resistance and surface finish.
Machining Pitfalls of Brass
Pitfall 1: Surface black spots, oxidation & patina
Causes: Residual cutting fluid, steel particle contamination, overheating during machining and incomplete cleaning.
Solutions:
  • Equipment: Dedicated machines/tools for brass, separate from steel part processing.
  • Cooling: Non-corrosive fully synthetic cutting fluid with controlled pH value and regular cleaning.
  • Post-treatment: Thorough cleaning + passivation + food-grade plating to eliminate patina.
Pitfall 2: Poor thread precision & water leakage failure
Solutions: High-precision taps/tools, stable machining parameters, dedicated fixtures and 100% go/no-go gauge inspection.
Machining Pitfalls of Aluminum Alloy
Pitfall: Tool sticking, surface white spots & oxidation
Solutions: Special aluminum alloy tools & cutting fluid, high rotating speed & large feed rate, timely cleaning and anodizing treatment.
Stamping/Deep Drawing (Outer casings, brackets, thin-walled parts)
Pitfall 1: Dimensional deviation & large springback (especially stainless steel)
Solutions: Die springback compensation, precise clearance (8%~12% of material thickness), additional shaping processes, stable blank holder force and stress relief treatment.
Pitfall 2: Wrinkling, cracking & burrs
Solutions: Reasonable die fillet radius, step-by-step deep drawing, high-quality lubrication, controlled stamping speed and timely deburring (vibratory grinding/polishing).
Welding & Assembly (Boilers, pipelines, structural components)
Pitfall 1: Weld porosity, slag inclusion & corrosion susceptibility
Solutions: Complete degreasing/oxide removal before welding, high-purity shielding gas, standardized welding parameters and post-weld pickling & passivation.
Pitfall 2: Assembly deformation & sealing failure
Solutions: Tooling positioning, step-by-step fastening, food-grade thread sealant application and pressure testing (1.5 times working pressure).
Surface Treatment (Core: Food Safety & Corrosion Resistance)
Pitfall 1: Plating peeling & heavy metal precipitation
Solutions: Food-grade nickel/chromium plating/passivation, strict coating thickness/adhesion/salt spray testing and compliance with food contact standards.
Pitfall 2: Rough surfaces, easy scaling & difficult cleaning
Solutions: Polishing with Ra≤0.8μm, electropolishing and passivation to improve surface finish and corrosion resistance.
Universal Non-Negotiable Machining Rules
  1. No mixed materials/production lines for food-contact parts: Separate production lines, tools and cutting fluids for stainless steel, brass and aluminum alloy to avoid cross-contamination.
  2. All coffee/water contact surfaces must be burr-free, sharp-edge-free, crack-free and residue-free, with 100% cleaning & inspection.
  3. Match materials with corresponding machining processes: Do not use brass machining parameters for stainless steel, or steel tools for brass processing, to prevent mass scrap loss.
  4. Full verification is mandatory: Material certificates, food contact safety testing, pressure testing, salt spray testing and service life testing.
