Injection Overmolded Magnet: One-Stop Solution from Magnet to Injection Molding

When you're looking for durable, precise, and application-ready magnetic components, injection overmolded magnet stands out as the game-changer for industries like automotive, electronics, and medical devices. Unlike traditional magnets that require extra assembly or coating, injection overmolded magnets combine strong magnetic performance with a protective, custom-molded plastic layer-solving common pain points like corrosion, vibration damage, and poor fit. And here's the best part: we offer a full one-stop service, covering every step from magnet selection to mold creation and final injection molding. No more coordinating with multiple suppliers-we handle it all for you.

Step 1: Custom Magnet Selection – The Foundation of Performance

Every great injection overmolded magnet starts with the right magnet core. We don't just offer "generic magnets"-we tailor the material, strength, and shape to your unique needs:

Magnet Material Options: Choose from high-performance neodymium (NdFeB) magnets for strong magnetic force (ideal for sensors or motors), ferrite magnets for cost-effectiveness (perfect for consumer electronics), or samarium cobalt (SmCo) magnets for extreme high-temperature resistance (critical for industrial machinery).

Precision Sizing: Whether you need tiny magnets for wearable devices or large components for automotive systems, we cut and shape the magnet core to your exact specifications-ensuring it fits seamlessly into the overmolding process later.

Performance Testing: Before moving to production, we test each magnet's magnetic flux density and durability. This step guarantees your injection overmolded magnet will meet long-term performance standards, even in harsh environments (like waterproof or high-vibration settings).

Step 2: Custom Mold Making – The Key to Perfect Overmolding

A high-quality injection overmolded magnet depends entirely on a precise mold. Our in-house mold engineering team turns your design into a production-ready mold-no outsourcing, no delays:

Design Collaboration: We work with your team to refine the mold design, considering details like plastic material compatibility (e.g., ABS, PP, or TPE for flexibility), wall thickness (to avoid cracking), and assembly features (like snap-fits or holes for easy installation).

High-Precision Manufacturing: Using CNC machining and EDM (Electrical Discharge Machining), we create molds with tolerances as tight as ±0.005mm. This precision ensures the plastic layer adheres perfectly to the magnet core, with no gaps or defects.

Mold Testing & Optimization: Before full production, we run test shots to check the mold's performance. If adjustments are needed (e.g., fixing flow marks or improving part release), we refine the mold on-site-saving you time and reducing waste.

Step 3: Injection Molding – Turn Design into Finished Injection Overmolded Magnets

Once the mold is ready, we move to the final step: injection molding. Our state-of-the-art molding facility ensures consistent, high-quality injection overmolded magnets batch after batch:

Plastic Material Expertise: We select the right plastic resin based on your application:

Use flame-retardant plastics for electronics (to meet safety standards).

Choose food-grade plastics for kitchen appliances or medical devices.

Opt for UV-resistant plastics for outdoor equipment (like solar panel components).

Automated, Controlled Production: Our injection molding machines are equipped with real-time monitoring systems-tracking temperature, pressure, and cycle time to ensure every injection overmolded magnet has uniform plastic coverage. No more uneven coating or weak adhesion.

Post-Molding Quality Checks: Each finished part goes through visual inspection, dimension measurement, and magnetic performance testing. We only ship injection overmolded magnets that pass 100% of our quality standards.

Why Choose Our One-Stop Injection Overmolded Magnet Service?

Coordinating with separate magnet suppliers, mold makers, and injection factories is a hassle-costing you time, money, and the risk of miscommunication. Our one-stop service eliminates these headaches:

Faster Turnaround: By handling all steps in-house, we cut lead times by 30% compared to multi-supplier setups. Get your injection overmolded magnets from design to delivery in weeks, not months.

Consistent Quality: No more "blame-shifting" between suppliers. We control every step, so your magnets, molds, and final parts meet the same high standards.

Customization for Every Industry: Whether you need injection overmolded magnets for automotive sensors (waterproof, shock-resistant), medical devices (biocompatible plastics), or consumer electronics (small, lightweight), we tailor the solution to your industry's unique requirements.
