Cost Calculation for Custom POM Parts
The cost of machining POM parts at Modo Rapid is determined by several key factors:
- Material Costs: The price of POM, which is relatively affordable, is a significant factor.
- Complexity of Design: Parts with intricate designs and tight tolerances require more time and specialized tools, increasing costs.
- Machining Time: Longer machining times due to POM’s properties and the need for precise operations.
- Surface Finishes: Additional processes such as polishing, painting, or coating add to the total cost.
- Tool Wear: POM’s properties lead to moderate tool wear, contributing to higher tool replacement costs.
Volume Discounts and Minimum Order Quantity
At Modo Rapid, we offer volume discounts to accommodate larger production runs. The discounts increase with the order size, making it more cost-effective for bulk purchases. We understand the diverse needs of our clients, so we have set a flexible minimum order quantity to cater to both small and large projects.
Example: Cost Calculation
Let’s assume we have a POM part with the following specifications:
- Dimensions: 100mm x 50mm x 10mm
- Complexity: Medium complexity geometry
- Surface Finish: Polished
- Quantity: 50 pieces
Material Cost
- Price of POM: $4/kg
- Weight per part: 0.2 kg
- Total material cost: 50 pieces x 0.2 kg x $4/kg = $40
Machining Cost
- Machining time for medium complexity parts: 0.5 hour/part
- Machining rate: $45/hour
- Total machining cost: 50 pieces x 0.5 hour/piece x $45/hour = $1,125
Surface Finish Cost
- Polishing cost: $1.50/piece
- Total surface finish cost: 50 pieces x $1.50/piece = $75
Tool and Equipment Wear
- POM causes minimal tool wear, but periodic replacement is necessary
- Estimated tool and equipment wear cost: $40
Other Costs
- Quality control and inspection fees: $100
- Packaging and shipping fees: $50
Total cost = Material cost + Machining cost + Surface finish cost + Tool and equipment wear + Other costs
Total cost = $40 + $1,125 + $75 + $40 + $150 = $1,430
Cost per part = Total cost / Quantity
Cost per part = $1,430 / 50 pieces = $28.60/piece
This example provides a rough estimate of the cost for CNC machined POM (Delrin/Acetal) parts. Actual costs will vary based on specific designs, process requirements, and quantities.

POM-C, or acetal copolymer, is produced through copolymerization, resulting in improved impact resistance, toughness, and chemical resistance compared to standard POM.
POM operates effectively up to 180° F (82° C) and offers excellent dimensional stability, high strength, and stiffness.
POM is highly durable, with significant impact resistance and fatigue resistance comparable to metals, making it suitable for applications where a lighter alternative to metal is needed.
POM is also known as acetal, polyformaldehyde, polyacetal, and polyformaldehyde. It is commonly available in black and white colors, though it can be produced in various hues.
POM operates within a temperature range of -40°C to 120°C. It has poor stability under acidic conditions and high temperatures.
POM-H (homopolymer) has greater hardness and stiffness compared to POM-C (copolymer). POM-H has a higher melting point (172-184°C) compared to POM-C (160-175°C) and slightly higher density and crystallinity.
POM has low adhesion due to its high chemical resistance, making it difficult to bond using adhesives.
Deformation can be caused by clamping, cutting heat, material elasticity, and internal stress. Each requires specific handling techniques to minimize deformation.
Post-rough machining annealing can be done via oil bath or air bath to reduce internal stress. Alternative methods include boiling in water or natural aging.
