About Julong Rubber
Custom Rubber Parts Manufacturer Since 1995
Julong Rubber manufactures custom molded, extruded and rubber-to-metal bonded components based on customer drawings, 3D models, physical samples and application requirements, supporting projects from technical review and tooling through sampling, production and repeat supply.
- Drawing and sample based development
- Custom OEM manufacturing
- Material and tooling review
- Inspection and export support
Manufacturing Capability
Custom Rubber Manufacturing from Development to Repeat Production
The manufacturing route is reviewed according to part geometry, material, tolerance, production quantity and application requirements rather than forcing every project into the same process.
- Custom rubber molding
- Rubber extrusion
- Rubber-to-metal bonding
- Tooling and mold development
- Sample development
- Trimming and secondary operations
- Dimensional and visual inspection
- Batch production and export packing
Manufacturing Process
From Drawing Review to Finished Rubber Parts
A structured development route helps turn customer requirements into controlled production while keeping technical, tooling and quality information aligned.
Drawing & Application Review
Review geometry, working conditions, quantity and critical requirements.
Material & Tooling
Confirm practical material options, hardness and tooling route.
Compound Preparation
Prepare rubber material according to the approved production requirement.
Molding or Extrusion
Form parts using the selected manufacturing method and tooling.
Secondary Operations
Trimming, cutting, joining, bonding or product-specific finishing.
Inspection
Dimensional, visual and agreed project-specific inspection checks.
Packing & Shipment
Batch identification, packing and shipment preparation for delivery.
Custom Rubber Components Across Multiple Product Families
Browse the main product categories used across sealing, machinery, automotive, HVAC, fluid handling and other industrial applications.
Quality & Documentation
Quality Documentation for Custom Rubber Projects
Material, inspection and compliance documentation can be reviewed according to the selected rubber compound, drawing, application, target market and project requirements.
Material Documentation
REACH, RoHS and available material-specific documentation can be reviewed according to the selected compound and project requirements.
Inspection Records
Dimensional, visual and agreed inspection records can be prepared according to drawings, product characteristics and customer requirements.
Project-Specific Testing
Required standards, test methods and documentation scope can be confirmed during RFQ, material review and sample development.
Documentation availability depends on the selected material, test scope and confirmed project requirements.
Engineering & Export Support
Clear Communication from RFQ to Repeat Orders
Custom rubber projects often depend on more than unit price. Drawings, materials, tooling, samples, inspection requirements and production quantities must remain aligned as a project moves forward.
Responsible Manufacturing
Environmental Equipment Is Part of Daily Factory Operations
Industrial exhaust collection and treatment equipment has been installed for production operations. The systems are operated during working days and are subject to supervision and periodic inspection by the local environmental authority.
- Industrial exhaust collection
- Treatment and filtration equipment
- Routine operation during production
- Local environmental supervision
