Custom Rubber Molded Parts for Industrial Machinery Details
FlexiTurn provides custom industrial rubber molding services, combining in-house CNC mold tooling with precision elastomer processing. The black components shown above—stepped flanged bushings, flat sealing rings, and square isolation pads—exemplify our capability to convert your 2D and 3D CAD models into durable, dimensionally consistent rubber parts engineered for shock absorption, mechanical sealing, and vibration isolation.
Material Selection GuideChoosing the right elastomer directly affects part lifespan and performance. Below is a quick reference for commonly molded materials:
| Elastomer | Hardness Range | Temp Range | Oil/Fuel Resistance |
| NBR (Nitrile) | 40–90 Shore A | -30°C to +100°C | Excellent |
| EPDM | 30–80 Shore A | -40°C to +150°C | Poor (water/ozone excellent) |
| FKM (Viton) | 50–90 Shore A | -20°C to +200°C | Excellent |
| Silicone (VMQ) | 20–80 Shore A | -60°C to +230°C | Poor |
| Neoprene (CR) | 40–90 Shore A | -30°C to +120°C | Good |
| Natural Rubber (NR) | 30–80 Shore A | -50°C to +80°C | Poor |
In-House CNC Tooling & Molding Process
CNC Mold Cavity Machining
The dimensional accuracy of molded rubber depends directly on mold tooling precision. FlexiTurn machines steel and aluminum mold cavities, core pins, and inserts in-house using high-speed 3/4/5-axis CNC milling and turning centers, maintaining tight cavity tolerances and smooth surface finishes on complex internal profiles, steps, and radii.
Concentric Core AlignmentPrecision CNC turning of mold cores ensures controlled concentricity between internal mounting bores and external flange surfaces—critical for smooth mechanical sub-assembly and uniform stress distribution in flanged bushings and stepped seals.
Molding Processes
- Compression Molding: Ideal for low-to-medium volumes, thick cross-sections, and large parts
- Rubber Injection Molding: Suitable for high-volume production, tight flash control, and complex geometries
- Transfer Molding: Used for parts with metal inserts or intricate internal features
Optimized mold parting design and controlled post-processing minimize flash on critical sealing surfaces, ensuring flat mating faces and clean internal diameters.
Tolerances & Quality Control
| Parameter | Specification |
|---|---|
| Molded Feature Tolerance | ±0.1 mm typical (geometry-dependent) |
| Mold Cavity CNC Accuracy | Down to ±0.005 mm |
| Hardness Range | 30–90 Shore A, custom durometers available |
| Surface Finishes | Smooth molded, matte, SPI mold textures, anti-static coatings |
Quality Verification:
- Shore A durometer hardness testing per batch.
- Non-contact optical profile measurement (primary method for soft elastomers).
- 3D CMM inspection for mold tooling and rigid inserts.
- Raw material batch certifications with every shipment.
- RoHS / REACH compliance documentation available upon request.
All processes are controlled under our ISO 9001:2015-aligned quality management system.

Q1. What types of machining services do you offer?
We provide comprehensive CNC turning and milling services. FlexiTurn machines are equipped with 8-station programmable turrets and support both turning and 5-axis milling operations, making them suitable for everything from simple cylindrical parts to complex multi-axis components.
Q2. What materials can you work with?
We machine a wide range of materials including carbon steel, stainless steel, aluminum, plastics, and other engineering-grade materials. If you have a specific material in mind, just send us your requirements and we'll confirm feasibility.
Q3. What is your typical lead time?
Lead times vary depending on part complexity, quantity, and material availability. For prototypes and small-batch runs, we typically deliver within 5–10 business days. For high-volume production, we'll provide a customized schedule after reviewing your drawings. Contact us with your project details for an accurate timeline.
Q4. How do you price your services?
Pricing is based on several factors: material cost, machining time, tooling requirements, setup complexity, and order quantity. We offer competitive rates for both low-volume prototypes and high-volume production runs. Request a quote with your CAD files or drawings and we'll get back to you within 24 hours.
Q5. What quality control measures do you have in place?
We follow strict quality control procedures throughout the machining process. Our CNC systems support programmable precision down to 1 μm, ensuring high accuracy and repeatability. Every batch undergoes dimensional inspection before shipping, and we can provide inspection reports upon request.
