Shenzhen
Direct-from-manufacturer production
Built for demanding environments
Components designed for chemical washdowns, temperature cycles, tight tolerances, and hygienic equipment requirements.
Engineered for uptime
Machined parts built for food processing machinery
Food sorting, processing, packaging, and conveying equipment operates under rigorous conditions. Frequent chemical washdowns, extreme temperature cycles, and strict hygienic requirements can expose weak materials or poorly finished parts.
We manufacture custom precision spacers, sleeves, bushings, standoffs, shafts, pins, and turned components from your 2D or 3D CAD models, material specifications, and surface finish requirements.

Material selection
Materials for hygienic and washdown environments
Material choice is essential for parts exposed to clean-in-place chemicals, steam, or direct food contact. Certified raw materials and material test reports are available upon request.
316 / 316L stainless steel
Exceptional resistance to pitting and corrosion caused by food acids, salt solutions, and harsh chlorine-based sanitation chemicals.
304 / 304L stainless steel
A standard choice for structural spacers, frame standoffs, and non-direct food contact components requiring reliable corrosion resistance.
POM, PEEK, and PTFE
Food-grade engineering plastics for self-lubricating wear sleeves, low-friction bushings, and electrical isolation spacers.
Aluminum alloys
6061-T6 and 7075 alloys for lightweight structural frames and non-contact moving parts, typically with hard anodizing.
Brass and copper
Precision spacers and fittings for liquid line valves or non-sparking mechanical subassemblies.
Production capabilities

Surface integrity
Post-processing for food industry requirements
Secondary processing helps machined components resist corrosion, reduce surface roughness, and prevent bacteria or debris buildup.
Passivation
ASTM A967 / A380 passivation removes free iron from stainless steel surfaces and enhances the natural chromium oxide protective layer after machining.
Precision grinding and polishing
Reduces surface roughness and eliminates micro-cavities where bacteria or debris can accumulate.
Hard anodizing
Type III hard anodizing creates a wear-resistant, non-reactive aluminum oxide layer for structural aluminum parts in washdown environments.
Laser marking
Applies part numbers, lot codes, or alignment marks permanently without introducing contamination hazards.
Why partner with us
Reliable support from prototype to production
Our Shenzhen facility combines direct communication, efficient lead times, and competitive production costs for engineering and sourcing teams.
Strict adherence to drawings
Manufacturing follows your specified tolerances, dimensions, material grades, and surface finishes.
High-mix production flexibility
Scheduling supports 10-piece machine-testing prototypes through 10,000-piece production runs.
Quality verification
Dimensional inspection uses calibrated micrometers, optical measuring instruments, and CMM equipment. Material certificates and inspection reports are available upon request.
Direct-from-manufacturer value
Work directly with the manufacturing source for efficient communication, lead times, and production costs.
SpacerMFG is the right partner if:
- ✓You are an OEM, machine builder, or engineering team designing or retrofitting food processing equipment.
- ✓You have 2D engineering drawings in PDF or DXF, or 3D models in STEP or IGES, ready for quotation.
- ✓Your application requires non-standard spacer lengths, custom wall thicknesses, custom steps, or specific stainless steel grades.
- ✓You need a reliable manufacturer that can transition parts from prototype validation to volume production.
We are not the right fit if:
- !You require standard off-the-shelf catalog hardware, such as DIN or ANSI washers supplied in small retail packaging.
- !You do not have dimensional specifications or technical drawings for the required components.
