Cost Calculation for Custom HDPE Parts
The cost of machining HDPE parts at Modo Rapid is determined by several key factors:
- Material Costs: The price of HDPE, 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 HDPE’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: HDPE’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
- Dimensions: 100mm x 50mm x 10mm
- Complexity: Medium complexity geometry
- Surface Finish: Textured
- Quantity: 50 pieces
Material Cost
- Price of HDPE: $2/kg
- Weight per part: 0.15 kg
- Total material cost: 50 pieces x 0.15 kg x $2/kg = $15
Machining Cost
- Machining time for medium complexity parts: 0.3 hour/part
- Machining rate: $35/hour
- Total machining cost: 50 pieces x 0.3 hour/piece x $35/hour = $525
Surface Finish Cost
- Texturing cost: $1.50/piece
- Total surface finish cost: 50 pieces x $1.50/piece = $75
Tool and Equipment Wear
- HDPE causes minimal tool wear, but periodic replacement is still necessary
- Estimated tool and equipment wear cost: $40
Other Costs
- Quality control and inspection fees: $80
- Packaging and shipping fees: $50
Total cost = Material cost + Machining cost + Surface finish cost + Tool and equipment wear + Other costs
Total cost = $15 + $525 + $75 + $40 + $130 = $785
Cost per part = Total cost / Quantity
Cost per part = $785 / 50 pieces = $15.70/piece
This example provides a rough estimate of the cost for CNC machined HDPE parts. Actual costs will vary based on specific designs, process requirements, and quantities.

FAQ
HDPE is commonly used in construction components like drain pipes, everyday home appliances, commercial containers, garbage bins, laundry detergent cartons, cutting boards, and milk cartons.
Compared to Low Density Polyethylene (LDPE), HDPE offers much greater impact resistance and tensile strength. It is better suited for applications requiring higher durability.
HDPE has a melt temperature of 266 F (130 C) and a tensile strength of 20 MPa (2,900 PSI).
- HDPE can be machined at tight tolerances and requires non-aromatic, water-soluble coolants for ideal surface finishes and close tolerances. It also has a very low coefficient of thermal linear expansion (CTLE), causing it to move with slight temperature changes.
Annealing reduces the chance of surface cracks and deformation due to internal stresses from the heat generated during machining. This process ensures higher quality precision machining.
Non-aromatic, water-soluble coolants such as pressurized air and spray mists are recommended to achieve the best surface finishes and extend tool life.
AIP designs, heat-treats, and machines only plastics with any sub-manufactured metalwork processed outside their facility to ensure the highest level of sanitation and prevent metallic cross-contamination.
Specialized polymer machining facilities ensure that there is no cross-contamination from metal machining fluids, which can cause cracks and other defects in plastic parts over time.
HDPE is available in three thicknesses: .250″ (6.35mm), .375″ (9.5mm), and .500″ (12.7mm).
The lead time for CNC machined HDPE parts is 2-4 days before shipping.
HDPE is resistant to molds, mildew, and other forms of rot, making it ideal for conditions with water transport or exposure. It is also non-toxic and non-staining.
HDPE is non-toxic and non-staining, making it safe for use in medical and food applications, such as reconstructive surgeries and food containers.
Yes, HDPE is easily recyclable and has a high strength-to-density ratio.
Yes, HDPE is compatible with most common chemicals, solvents, acids, detergents, and cleaning fluids.
HDPE has a tensile strength (ultimate) of 3.4-4.6 ksi, shear strength of 2 ksi, and elongation at break of 600%. It has a melting point of 260°F and a continuous service temperature of 180°F.
