Customized High Precision Black Rubber Bushing Details
FlexiTurn manufactures custom compression-molded rubber bushings and elastomer components, extending our precision machining heritage into full-spectrum elastomer manufacturing. With in-house mold design, CNC-machined tooling, and controlled vulcanization, we deliver bonded rubber-metal assemblies and pure elastomer parts from prototype to high-volume production — serving automotive, automation, aerospace, and oil & gas industries.
Capabilities Overview
Rather than off-the-shelf catalog parts, FlexiTurn provides contract manufacturing of custom elastomer components engineered to your drawings and performance specifications. Our vertically integrated capability — from CNC-machined mold cores and metal bonding substrates to precision molding and post-processing — enables hybrid rubber-metal solutions that few standalone rubber shops can deliver.
Core Manufacturing Processes:
Compression Molding: Standard for low-to-medium volume and large cross-sections; optimal for prototype and short-run tooling.
Transfer Molding: Medium-to-high volume; tighter cavity fill control for complex geometries and bonded inserts.
Injection Molding: High-volume automation; consistent cycle times and minimal flash for precision small parts.
Post-Processing: Cryogenic deflashing, die-cut trimming, and precision CNC turning for high-durometer (≥Shore A 80) or metal-bonded components requiring tight dimensional control.
Note on CNC Machining: Our CNC turning capability is applied to high-durometer polyurethane, rigid polymer, and rubber-metal bonded components where machined finishes are required. Standard soft-elastomer parts are finished via cryogenic deflashing or die cutting — not CNC.

FlexiTurn Advantage
We manufacture the metal inner/outer sleeves in-house on CNC lathes (±0.005 mm), then chemically treat and bond elastomer to the metal via controlled vulcanization. Single integrated component with precision concentricity, full traceability, and no third-party metal supplier dependency. Ideal for automotive control-arm bushings, suspension strut mounts, and industrial vibration isolators.

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.
