Transform the strength and longevity of your plastic assemblies with our premium Brass Inserts. Engineered for superior thread integrity, these inserts provide robust, reusable, and wear-resistant fastening points in a wide range of soft materials, including thermoplastics, thermosets, 3D printed parts, and wood composites. Say goodbye to stripped threads and unreliable connections – our brass inserts are the ultimate solution for enhanced product durability and easier assembly.
Key Features & Benefits:
Superior Thread Strength & Durability: Create high-strength, reusable metal threads in softer materials that are prone to wear and stripping. Ideal for frequent assembly and disassembly.
Optimal Material (Brass): Crafted from high-quality brass (typically CDA 360 or similar lead-free alloys), offering excellent machinability, corrosion resistance, good thermal and electrical conductivity, and a pleasing aesthetic.
Enhanced Pull-Out & Torque Resistance: Featuring advanced knurling patterns (straight, diagonal, diamond) designed to maximize grip within the parent material, ensuring reliable performance under stress.
Versatile Installation Methods: Compatible with various common installation techniques, including heat-staking, ultrasonic insertion, press-fit, and molding-in, allowing flexibility in your manufacturing process.
Reduced Assembly Time & Cost: Facilitate faster, more reliable assembly processes, minimizing rework and material waste.
Clean & Flush Finish: Many designs feature a pilot or flange for easy alignment and a professional, flush finish with the surface of your component.
Wide Range of Sizes: Available in a comprehensive selection of metric (M1.6 to M10) and imperial (#2-56 to 1/2"-20) thread sizes to suit diverse application requirements.
RoHS & REACH Compliant: Manufactured to meet strict environmental and safety standards, ensuring suitability for a global market.
Ideal Applications:
Our Brass Inserts are indispensable across a multitude of industries and products, including:
Electronics Enclosures: Laptops, routers, smartphones, IoT devices, control panels.
3D Printed Parts: Strengthening threads in FDM, SLA, SLS, and other additive manufactured components.
Prototyping & Small-Batch Production: Quick and reliable thread creation for new designs.
Types & Installation Methods:
We offer a variety of brass insert types, each optimized for specific installation processes:
Heat-Set / Ultrasonic Inserts:
Design: Typically feature a pilot lead for easy alignment and multi-directional knurling (e.g., straight, diagonal, or spiral) to maximize resistance to pull-out and torque.
Installation: Inserted into a pre-drilled or molded hole using heat (heat-staking) or ultrasonic vibrations. The heat/vibration momentarily softens the surrounding plastic, allowing the insert to be pressed in, with the molten plastic flowing into the knurls for a secure lock.
Benefits: High performance, rapid installation, ideal for mass production.
Molded-In Inserts:
Design: Often feature diamond knurling and a through-hole design.
Installation: Placed into the mold cavity before plastic injection. The molten plastic flows around and into the knurls of the insert, creating an extremely strong, integrated connection.
Benefits: Maximum strength and pull-out resistance, fully encapsulated.
Press-Fit Inserts:
Design: Feature aggressive knurling and often a lead-in chamfer.
Installation: Simply pressed into a slightly undersized hole. The knurling deforms the plastic to create an interference fit.
Benefits: Economical, simple installation for non-critical applications or materials with sufficient elasticity.
Self-Tapping Inserts (Less Common for Brass, but available):
Design: Feature external cutting threads that tap their own threads into the base material as they are screwed in.
Installation: Driven into a pre-drilled hole using a screwdriver or power tool.
Benefits: Excellent for field repairs or materials that require a specific thread pitch.
