Modern industrial machinery increasingly uses engineered plastics, composite materials, and lightweight components for housings, guards, control systems, sensors, and internal assemblies.
These materials can reduce weight, improve corrosion resistance, provide electrical insulation, and simplify component manufacturing.
Product Specification
Modern industrial machinery increasingly uses engineered plastics, composite materials, and lightweight components for housings, guards, control systems, sensors, and internal assemblies.
These materials can reduce weight, improve corrosion resistance, provide electrical insulation, and simplify component manufacturing.
However, plastic components can present a fastening challenge.
Directly tapping threads into polymer materials may not provide the durability required for repeated assembly, maintenance, vibration, or higher mechanical loading.
Industrial threaded inserts provide a practical solution by creating a durable internal metal thread inside a plastic component.
The insert, plastic boss, installation method, and mating screw should be considered together as a complete fastening system.
Industrial control equipment such as HMI panels, PLC housings, push-button control boxes, and operator interfaces often combine plastic housings with metal fastening points.
Threaded inserts can provide repeatable threaded connections for:
• Control panels
• HMI housings
• PLC enclosures
• Operator interfaces
• Electrical control boxes
• Internal mounting brackets
Automation equipment and robotic systems frequently use lightweight plastic covers, brackets, sensor mounts, and protective components.
Typical applications include:
• Robotic equipment covers
• End-of-arm tooling components
• AGV and AMR housings
• Pneumatic actuator brackets
• Sensor mounting components
• Automation equipment panels
Threaded inserts can help support repeated assembly and maintenance where components may need to be removed and reinstalled during equipment servicing.
Industrial equipment is often designed for maintenance and component replacement. Screws may need to be removed and reinstalled during the service life of the equipment.
Compared with directly tapped plastic threads, a metal threaded insert provides a more durable threaded interface and can help support repeated assembly and disassembly.
The correct insert design depends on:
• Thread size
• Insert length
• Plastic material
• Boss dimensions
• Installation method
• Assembly torque
• Service requirements
Machinery, automation equipment, pumps, motors, fans, and robotic systems may operate under continuous vibration or dynamic loading.
For these applications, the insert profile, plastic boss design, mating screw, and assembly conditions should be considered as one fastening system.
Proper insert geometry and sufficient engagement with the surrounding polymer can help improve resistance to rotation and pull-out under the specified application conditions.
Brass threaded inserts are widely used because they provide a practical balance of machinability, mechanical performance, corrosion resistance, and electrical conductivity.
They are commonly considered for:
• Electronic housings
• Industrial control equipment
• Automation components
• Sensor housings
• Plastic enclosures
• Electrical equipment
Stainless steel threaded inserts can be considered when higher corrosion resistance or greater environmental durability is required.
Potential applications include:
• Outdoor industrial equipment
• HVAC systems
• Washdown environments
• Industrial machinery
• Chemical-processing equipment
• Marine or humid environments
Aluminum threaded inserts can be considered where weight reduction is important.
Typical applications may include:
• Robotics
• Automation equipment
• Lightweight machinery
• Portable industrial equipment
• Aluminum and polymer assemblies
Heat staking is widely used for thermoplastic components.
The insert is heated and positioned into a prepared plastic boss. The surrounding polymer softens and flows around the external insert geometry before cooling and solidifying.
Ultrasonic insertion uses controlled ultrasonic energy to soften the surrounding thermoplastic material and install the insert.
This process can be suitable for applications requiring efficient assembly and consistent positioning.
Press-fit installation can be considered when the plastic material and component design provide sufficient interference and retention.
Important design factors include:
• Hole diameter
• Interference level
• Plastic hardness
• Boss geometry
• Installation force
• Required retention performance
Industrial equipment may be exposed to humidity, condensation, chemicals, outdoor environments, cleaning processes, or other corrosive conditions.
JUXIN can provide customized plating and surface treatment solutions according to customer requirements.
For demanding applications, salt spray performance of up to 1,200 hours can be achieved when specified by the customer, depending on the substrate, coating system, and applicable testing requirements.
Surface treatment should be selected according to the actual operating environment rather than applying the same coating specification to every application.
Industrial OEMs often require threaded inserts that differ from standard catalog products.
JUXIN can support customized threaded insert requirements based on:
• 2D engineering drawings
• 3D CAD files
• Samples
• Thread specifications
• Insert dimensions
• External geometry
• Material requirements
• Surface treatment
• Installation method
• Production volume
Custom features may include modified lengths, diameters, thread specifications, external profiles, flanges, and other application-specific geometries.
Different plastics behave differently during insertion and under mechanical loading. Engineers should consider the polymer type, reinforcement, hardness, temperature resistance, and dimensional stability.
The boss surrounding the insert must provide sufficient material to support installation and service loads.
External geometry influences the interaction between the insert and surrounding plastic. Knurling, grooves, undercuts, and other retention features may be considered depending on the installation method and application.
The specified screw torque should be compatible with the insert, plastic component, and overall joint design.
Where mechanical loads are significant, pull-out and torque-out performance should be evaluated according to the application's actual requirements.
Industrial procurement teams normally require consistent dimensions, stable production quality, reliable supply, and clear technical communication.
For OEM threaded insert programs, important considerations include:
• Dimensional consistency
• Material control
• Surface treatment consistency
• Thread quality
• Production repeatability
• Packaging requirements
• Inspection requirements
• Drawing and sample approval
• Batch identification where required
JUXIN supports OEM fastener production using manufacturing processes including cold forging, CNC machining, stamping, injection molding, and customized fastener production.
Industrial fastening projects often begin with an engineering drawing or prototype and later move into larger production volumes.
A practical development process can include:
Review the application and engineering requirements
Confirm plastic material and component design
Select insert material and installation method
Develop or modify the insert geometry
Produce samples
Evaluate fit and assembly performance
Confirm production specifications
Move into production and quality control
Early cooperation between the insert supplier, structural engineer, and manufacturing team can help avoid fastening problems after tooling or mass production has already started.
JUXIN supports industrial OEM customers with standard and customized threaded insert solutions for plastic and composite components.
Our manufacturing capabilities include cold forging, CNC machining, stamping, injection molding, and custom fastener production.
We work with customers on insert dimensions, materials, external geometry, surface treatment, installation methods, and application requirements.
The goal is not simply to supply a threaded insert, but to help develop a fastening solution that fits the customer's component design and production process.
Industrial threaded inserts can support fastening requirements across a wide range of industrial sectors, including:
• Industrial automation
• Robotics
• Electrical equipment
• Power electronics
• HVAC
• Industrial machinery
• Sensors and instrumentation
• Telecom equipment
• Control systems
