Low Volume Production

Perfect for low-volume runs, product launches, or bridge production. Cast 20 to 200+ parts with consistent quality and quick turnaround—skip the wait for injection molds.

Mass Production

For larger production needs, we offer injection molding to create high-volume plastic parts with consistent quality and lower unit cost.

Certified Quality Control and Testing

XCD operates as an ISO 9001:2015, ISO 13485, ISO14001:2015, and IATF 16949:2016 certified vacuum casting manufacturer. Our quality control covers three critical areas:

Dimensional Testing

Dimensional testing uses CMM, digital calipers, height gauges, and micrometers to verify tolerances, geometric positioning, hole diameters, wall thickness, and fit dimensions.

Visual Inspection

Visual inspection employs magnifiers, roughness testers, and color charts to detect surface defects including bubbles, scratches, dents while ensuring color consistency and surface finish quality.

Paint Adhesion Testing

Paint adhesion testing validates coating bond strength, durability, and thickness uniformity for all finishing requirements.

Assembly & Fit Validation

Verifies cast parts’ mating compatibility and functional fit with paired components. Conducts precision fit tests to ensure seamless groove, joint and structure matching, meeting assembly requirements and eliminating fit gaps or interference.

What's Urethane Casting Process?

Urethane casting, also called vacuum casting, draws liquid urethane into a mold to create plastic and rubber parts with intricate geometries. Here are the 3 steps.

1Master Patterns

The master pattern replicates the final casting parts, determining product quality. Create it via CNC machining or 3D printing. 3D printing is faster and cheaper, but CNC offers tighter tolerances. Design considerations include draft angles and wall thickness.

2Solicone Mold Casting

Pour liquid silicone rubber around the master pattern. Most cure in ovens, while RTV molds cure at room temperature. After a few hours, cut along the parting line to remove the master, creating a silicone mold ready for casting.

3Urethane Pouring and Finishing

Mix liquid polyurethane resin and pour into molds under vacuum to prevent air bubbles and defects. Curing takes 30 minutes to 2 hours depending on material and size. One mold produces 1-10 copies daily. Cast urethane parts may require post-processing.

Vacuum Casting Applications Across Industries

Urethane casting is good for prototypes and small production runs where injection mold tooling isn’t practical. Cast part perform well and can be used for testing or as finished products.

| Automotive

Interior trim panels, dashboard components, and functional prototypes for fit-and-finish testing.

| Medical & Healthcare

Biocompatible device housings, surgical instrument prototypes, and diagnostic equpment.

| Electronics & Consumer Products

Product enclosures, keypads, and decorative elements for smarphones, tablets, and home appliances.

| Aerospace

Lightweight interior panels, control housings, and specialized components requiring flame-retardant properties.

| Industrial Equipment

Machine guards, control panels, and custom tooling fixtures.

Vacuum Casting FAQs

How long does it take to receive a part once an order is placed?

The lead time for receiving a CNC machined part from XCD can vary depending on several factors including the complexity of the part's design, the type of material selected, and our current production schedule. CNC machining is known for its speed, particularly for less complex parts, allowing for quick turnaround times. In fact, parts can be delivered in as fast as just one day after the machining setup is complete! However, for the most accurate time estimate tailored to your specific project, we recommend contacting us directly for a detailed quote. This way, we can provide you with a precise timeframe based on your unique requirements.

How much does your CNC machining service cost?

At XCD, every product goes through strict verification—from trial production and inspection testing to customer confirmation—before shipment. Our quality assurance process ensures that all parts meet the agreed specifications before delivery, minimizing the risk of nonconformities. We take pride in our precision and reliability, and every shipment is the result of a joint confirmation between our engineers and customers.

Is there a minimum order quantity (MOQ) for CNC machining at XCD?

At XCD, we understand the diverse needs of our customers, ranging from single prototypes to large-scale production runs. Consequently, we do not enforce a strict minimum order quantity (MOQ). Whether you require just one machined part or thousands, we are equipped and ready to provide tailored solutions that meet your specific requirements.
