The Injection Molding Process
Our streamlined injection molding process ensures precision, efficiency, and consistent quality from design to delivery.
Design & Engineering
Our engineering team collaborates with you to refine your part design for manufacturability, ensuring optimal mold flow, material selection, and cost efficiency.
Injection Molding
Molten plastic is injected into the mold cavity under precise pressure and temperature conditions. The material cools and solidifies into the desired part shape.
Mold Design & Fabrication
We design and manufacture precision molds using advanced CNC machining and EDM processes, ensuring durability and dimensional accuracy for consistent part production.
Part Ejection & Inspection
Finished parts are ejected from the mold and undergo rigorous quality inspection to ensure they meet all specifications and tolerances.
Material Preparation
Plastic resins are carefully selected, dried if necessary, and prepared for molding. Colorants and additives are precisely mixed to achieve the desired properties.
Finishing & Assembly
Parts may undergo additional processing such as surface treatment, painting, or assembly before final packaging and delivery.

Custom Injection Molding Design Guidelines
Proper design is critical for successful injection molding. Follow these guidelines to optimize your part design for manufacturability, cost, and performance.
Wall Thickness
Maintain uniform wall thickness throughout your part to prevent sink marks, warping, and internal stresses.
- Keep wall thickness between 0.8mm and 3mm for most applications
- Maximum thickness variation should not exceed 25%
- Use gradual transitions between different wall sections
Undercuts
Minimize or avoid undercuts whenever possible, as they complicate mold design and increase cost.
- Consider alternative designs that eliminate undercuts
- Use side actions or lifters for necessary undercuts
- Threaded features often require unscrewing mechanisms
Draft Angles
Include proper draft angles on all vertical surfaces to facilitate easy part ejection from the mold.
- Minimum draft angle of 0.5° per side for most applications
- Increase draft angle for deeper cavities and textured surfaces
- Consider 1°-2° draft for parts with tight tolerances
Ribs & Bosses
Use ribs to increase part stiffness without increasing wall thickness. Bosses provide strong mounting points.
- Rib thickness should be 50-70% of the nominal wall thickness
- Height of ribs should not exceed 3 times the wall thickness
- Bosses should have a diameter 2-3 times the hole diameter
Radii & Fillets
Use generous radii and fillets at all corners to improve part strength and mold filling.
- Minimum internal radius of 0.5mm
- External radii should be at least 1.5 times the wall thickness
- Sharp corners create stress concentrations and molding difficulties
Parting Lines
Consider the location of parting lines early in the design process to minimize their visual impact.
- Place parting lines in less visible areas when possible
- Design for a straight, simple parting line if possible
- Account for potential flash along the parting line

Injection Molding FAQs
1-3 weeks for prototype production. Once tooling is completed, production typically takes 1-2 weeks for small to medium runs, and larger runs can be completed in several weeks depending on order size.
Design limitations involve factors such as mold flow, part ejection, and cooling efficiency. To ensure successful molding, designs should minimize undercuts, maintain consistent wall thickness, and incorporate draft angles for easy part removal.
The minimum order quantity depends on the specific project. We offer flexibility to handle both small batch and high-volume production, tailored to meet the unique requirements of each client.
We are committed to delivering the highest quality parts right from the start. That’s why Fecision offers DFM analysis at no charge, ensuring you have all the confidence you need before placing your injection molding order.
