Typical Lead Times and Cost Ranges
When planning to manufacture plastic molds, understanding lead times and cost factors helps in project planning and budgeting.
| Mold Complexity | Typical Lead Time | Cost Range (USD) | Annual Volume Suitability | Features |
|---|---|---|---|---|
| Simple (1-2 cavities) | 2-4 weeks | $5,000 - $15,000 | 10,000 - 100,000 | Basic geometry, no slides |
| Medium (4-8 cavities) | 4-8 weeks | $15,000 - $50,000 | 100,000 - 500,000 | Some complexity, basic slides |
| Complex (8+ cavities) | 8-16 weeks | $50,000 - $150,000 | 500,000 - 2,000,000 | Multiple slides, complex geometry |
| Highly Complex | 16+ weeks | $150,000+ | 2,000,000+ | Hot runners, unscrewing mechanisms, complex cooling |
Frequently Asked Questions About Manufacture Plastic Molds
Several factors influence the cost when we manufacture plastic molds, including the size and complexity of the part design, number of cavities, material selection for the mold, required tolerances, surface finish requirements, and any special features like hot runners or complex cooling systems. Additionally, production volume expectations affect mold design and material choices, impacting overall cost.
The lifespan of a mold depends on several factors, including the material used to manufacture plastic molds, the type of plastic being molded, production volume, and maintenance practices. Generally, aluminum molds last 10,000-50,000 cycles, while pre-hardened steel molds can last 100,000-500,000 cycles. High-grade tool steels can endure 1,000,000+ cycles with proper maintenance. Regular cleaning, inspection, and preventive maintenance can significantly extend a mold's useful life.
When designing parts for which we will manufacture plastic molds, several considerations are critical: draft angles to facilitate part ejection, uniform wall thickness to prevent warping, appropriate radii at corners to reduce stress concentrations, and consideration of gate placement for proper material flow. Additionally, designers should account for shrinkage rates of the chosen plastic material and ensure that the part geometry can be properly cooled during the molding process. Collaborating with mold manufacturers early in the design process can optimize these factors.
To reduce costs when you manufacture plastic molds, consider simplifying part geometry where possible, maintaining uniform wall thickness, and minimizing undercuts that require complex mold mechanisms. Selecting the appropriate mold material based on expected production volume can also reduce costs—using aluminum for low-volume production instead of steel, for example. Additionally, designing parts with manufacturability in mind from the beginning and engaging with your mold manufacturer early in the design process can identify cost-saving opportunities before production begins.
Lead times to manufacture plastic molds vary based on complexity, size, and material. Simple molds with 1-2 cavities typically take 2-4 weeks, while medium-complexity molds may take 4-8 weeks. Complex molds with multiple cavities, hot runners, or special features generally require 8-16 weeks or more. Rush options may be available for an additional cost, potentially reducing lead times by 30-50%. It's important to factor in time for design reviews, prototyping, and testing when planning your project timeline.
Glossary of Terms
Cavity
The hollow part of a mold that shapes the exterior of the plastic part when molten plastic is injected.
Core
The part of the mold that forms the interior surfaces of the plastic part.
Draft Angle
A slight taper applied to vertical surfaces of the mold to facilitate easy ejection of the part without damage.
Ejection System
Mechanism in the mold that pushes the cooled plastic part out of the cavity after molding.
Gate
The opening through which molten plastic enters the mold cavity.
Hot Runner System
A system that keeps the plastic molten in the runner system while the part cools, eliminating waste from solidified runners.
Undercut
A feature in a part that prevents it from being directly ejected from a simple two-piece mold, requiring additional mold mechanisms.
Venting
Small channels in the mold that allow air to escape as molten plastic fills the cavity, preventing defects.
