What Is Injection Molding?
Injection molding is a manufacturing process where molten plastic is injected into a precision-engineered mold to form parts. It excels at producing consistent, high-quality components in medium to high volumes, where mold design, material selection, and processing parameters work together for durability, accuracy, and repeatability.
The process is ideal for complex plastic parts that need tight tolerances, excellent surface finish, and reliable performance across large production runs, with per-part cost dropping as volume rises.
Plastic Injection Molding Services for Custom Parts
Injection Mold Tooling
Precision aluminum and hardened-steel molds designed for durability, repeatability, and consistent performance across production cycles. Aluminum tooling suits rapid and low-volume work, while hardened steel serves high-volume production.
Surmoulage
Overmolding combines multiple materials into a single part, molding a second material over a substrate to improve grip, sealing, strength, and product functionality.
Insert Molding
Insert molding integrates metal or other components into a plastic part, building strong metal-to-plastic features while reducing assembly steps and cost.

Foire aux questions
How much does injection molding cost?
Injection molding cost splits into two parts: a one-time tooling (mold) cost and a low per-part cost that repeats every cycle. The mold is the big upfront number, and it can run from roughly a thousand dollars for a simple aluminum tool to tens of thousands for a multi-cavity steel tool. Because the tooling cost spreads across every part you make, the per-part price drops sharply as volume rises, which is why molding beats machining at scale. Send your CAD, target quantity, and material and we return an itemized quote with tooling, per-part price, and lead time.
Should I use an aluminum or steel mold?
It depends on your volume and how long the tool must last. Aluminum molds are cheaper and faster to cut, which makes them ideal for low volume injection molding services, bridge production, and design validation, typically up to several thousand parts. Hardened steel molds cost more upfront but survive hundreds of thousands to millions of shots, so they win on cost per part at high volume. We support both aluminum for rapid tooling and hardened steel for production, and we recommend the right one for your quantity during DFM.
How do single-cavity, multi-cavity, and family molds affect cost?
A single-cavity mold makes one part per cycle and costs the least upfront, which suits prototypes and low volumes. A multi-cavity mold makes several identical parts per cycle; it costs more to build but slashes per-part cost, and it usually pays off above about 10,000 parts. A family mold makes several different parts in one cycle, handy for a matched set or assembly. We support single-cavity, multi-cavity, and family molds and size the cavitation to your annual volume so the tooling investment matches the payback.
What is the minimum order quantity for injection molding?
There is no hard minimum, but because the mold is a fixed cost, very small runs carry a high per-part price. For a handful of parts, CNC machining or 3D printing is often cheaper than cutting a mold. Molding starts to win once you need repeatable parts in the hundreds to thousands, and it dominates at higher volumes. If you are unsure, send your quantity and we will tell you honestly whether a mold, a bridge tool, or machining is the lowest-cost route for your stage.
How do I reduce injection molding cost?
Most savings come from the part design, not the negotiation. Uniform wall thickness prevents warping and shortens cooling time, coring out thick sections cuts material and cycle time, generous draft and fewer undercuts simplify the tool, and dropping unnecessary cosmetic finishes lowers tooling effort. Choosing a commodity resin over a high-performance one when the application allows also helps. Our DFM feedback flags these opportunities on your specific part, and design changes made before the mold is cut are far cheaper than changes after.
What is the difference between overmolding and insert molding?
Both combine materials, but they differ in what goes into the mold. Overmolding molds a second material over an existing plastic or metal substrate, commonly a soft grip over a rigid handle, improving comfort, seal, or strength. Insert molding places a pre-made component, often a metal threaded insert or terminal, into the mold so the plastic forms around it, which builds strong metal-to-plastic features and reduces assembly. We offer both, and during DFM we advise which suits your part and how to design the bond or retention feature.
What is LSR (liquid silicone rubber) molding and when should I use it?
LSR molding injects a two-part liquid silicone that cures into a flexible, heat-resistant, biocompatible rubber part, unlike rigid thermoplastics. It is the right choice for seals, gaskets, valves, wearables, and medical or baby-care parts that need flexibility, chemical resistance, and a wide temperature range. Our rubber injection molding services cover LSR alongside standard thermoplastic molding, so we can match the material to the function. If your part needs to flex, seal, or tolerate heat, LSR is usually the answer, and we can quote it from your CAD.
What causes defects like sink marks and warping, and how do you prevent them?
Most molding defects trace back to uneven wall thickness and cooling. Thick sections cool slower and pull inward, causing sink marks, while uneven shrinkage across the part causes warping. We prevent them with uniform walls, coring out thick areas, proper gate placement, and controlled cooling, and we use mold flow analysis to predict fill and shrink before cutting steel. Ribs and bosses are sized to avoid witness marks. Catching these in DFM is far cheaper than fixing a mold, so we review your part for defect risk up front.
Quelle épaisseur de paroi et quel angle de dépouille ma pièce doit-elle avoir ?
For most thermoplastics we recommend a wall thickness between 0.6 mm and 4.5 mm, kept as uniform as possible, since thin, even walls cool evenly and mold cleanly. Draft angle should be about 1 to 3 degrees on walls perpendicular to the pull direction so parts release from the mold without drag marks or damage. Ribs and gussets work best around 0.6 to 2.5 mm, and bosses from 3 to 12 mm in diameter. Send your model and our DFM review flags any walls, drafts, or ribs that need adjusting before tooling.
Do you offer bridge tooling to start production faster?
Yes. Bridge tooling uses a fast, lower-cost aluminum mold to produce real molded parts while your production steel tool is still being built, so you can launch or run market tests without waiting weeks for hard tooling. It is also ideal for validating fit and function before committing to an expensive production mold. Because we cut aluminum tooling in-house, we can move from approved design to first molded parts quickly. Tell us your timeline and volume and we will lay out a tooling path that fits both.
