In the electronics industry, electrical equipment, and machinery manufacturing, FR4 material is widely used in the production of various structural components due to its excellent mechanical properties and electrical insulation characteristics. If you are looking for reliable FR4 machining customization services, in addition to standard products, we can also provide customized machining of high-precision insulation structural components according to complex design requirements.
As a professional manufacturer, we specialize in the precision machining of FR4 (epoxy fiberglass laminate) and its derivative materials, providing integrated services from design optimization to mass production.
FR4 is a composite material with fiberglass cloth as reinforcement and epoxy resin as the matrix. It has a good balance between electrical and structural performance, making it suitable for various industrial scenarios.
FR4 material has high volume resistivity and dielectric strength, which can meet the insulation requirements of low-voltage and some medium-voltage electrical systems, reducing safety hazards such as leakage or breakdown.
High-precision insulation structural components typically need to balance insulation and load-bearing functions. FR4 possesses excellent bending strength and dimensional stability, and can be processed into: Insulating supports, Partitions and mounting structures, Power device mounting components.
FR4 material exhibits excellent heat resistance and flame retardancy. It is widely used in switchgear, transformers, power electronic equipment, and other applications requiring long-term operation.
We understand the precision requirements of equipment assembly. Whether it’s a simple gasket or a complex irregularly shaped structural component, we strictly adhere to tolerance standards during machining to ensure products meet usage requirements.
We utilize multi-axis CNC machining, optimizing the machining process based on the characteristics of FR4 material to reduce issues such as chipping and delamination. Machining accuracy can reach ±0.05mm, ensuring accurate fit of insulating structural components.
Depending on application requirements, we offer the following surface treatments:
Grinding and chamfering to remove burrs and smooth edges
Drilling and countersunk machining to meet installation requirements
Silk screen printing and laser marking for easy traceability and identification
Our engineering team can provide manufacturability advice during the design phase, optimizing drawings while ensuring structural strength, reducing machining difficulty and costs.
Requirement Communication: Provide 2D/3D drawings (DWG, STEP, PDF format) or samples, and we will conduct technical coordination.
Material Selection: Recommend suitable sheet metal based on requirements such as temperature resistance, thickness (0.5mm–50mm), and color (yellow/black/white).
Sample Confirmation: Quickly complete sampling to facilitate verification of dimensions and strength.
Mass Production: Use automated production lines to ensure product consistency, free of burrs and scratches.
Factory Inspection: Confirm dimensions through full inspection or random sampling, and provide material certification reports.
