One-Step Service from Prototyping to Production

Samshion offers full support for your entire product lifecycle from sample making to volume production.

CNC-machined metal components with different colors and surface appearances

Rapid Prototyping

Validate form, fit, assembly and functional intent before investing in production tooling. Depending on the test objective, the route may use CNC machining, 3D printing, sheet metal fabrication or vacuum casting.

Low-Volume and Repeat Production

Move a released design into pilot quantities or repeat orders with controlled revisions, confirmed materials, defined finishes and an agreed inspection scope. Dedicated fixtures or tooling may be recommended when they improve consistency or unit economics.

Samshion's Capabilities

We committed to providing custom manufacturing solutions perfectly adapted to each client’s unique requirements. Every project is assigned a dedicated project manager and backed by a professional expert team fully organized for your project. Covering the entire process from prototyping through mass production, we adopt cutting-edge manufacturing technologies to consistently deliver premium quality that surpasses customer expectations

CNC Machining

Multi-axis milling and CNC turning for custom metal and engineering-plastic components, from individual prototypes to repeat production. Feature-level tolerance capability is reviewed from the drawing rather than promised as one universal value.

Injection Molding

Tooling and molded plastic parts for designs that have reached suitable maturity and quantity. DFM review covers draft, wall thickness, ribs, bosses, gates, ejection, resin behavior and appearance requirements.

Sheet Metal Fabrication

Laser cutting, bending, hardware insertion, welding and finishing for brackets, panels, frames, covers and enclosures. Drawings should identify material thickness, bend requirements, hardware, welds and cosmetic surfaces.

3D Printing

Additive manufacturing for fast design iteration, complex geometry, assembly checks and selected end-use applications. The process and material are chosen around strength direction, surface, dimensional needs and test purpose.

Vacuum Casting

Polyurethane parts reproduced from a master pattern for small batches of appearance models and functional prototypes. Casting materials can simulate selected characteristics of molded plastics but are not automatically identical to production thermoplastics.

Aluminum Extrusion

Custom and standard aluminum profiles with secondary cutting, CNC machining and finishing. Die requirements, alloy, temper, quantity, profile geometry and finish are reviewed before quotation.

Why Choose Samshion?

A successful manufacturing project requires more than machine capacity. It requires clear communication, practical engineering feedback and quality controls that remain consistent from quotation through delivery.

Process Selection Based on Your Part

We evaluate geometry, material, tolerance, quantity and finishing requirements before recommending a manufacturing process.

DFM Review Before Production

Our engineers identify tolerance conflicts, thin walls, inaccessible features, tooling risks and unnecessary cost before manufacturing begins.

One Project Contact

A dedicated contact coordinates technical questions, quotation details, production updates, inspection requirements and shipment information.

Support from Prototype to Production

Keep the same manufacturing partner as your project moves from design validation to pilot production and repeat orders.

From CAD File to Delivered Parts

Simplified, Transparent, Reliable, Simple as 1-2-3-4

A clear four-step workflow keeps technical requirements, production status and quality documentation aligned throughout your project.

Upload Your Files

Send your CAD files, drawings and project requirements. Include the required material, quantity, tolerance and finish whenever available.

Quote + DFM Feedback

Our team reviews manufacturability, confirms the production process and provides pricing, lead time and engineering feedback.

Approve and Start Production

After the quotation, specifications and purchase order are approved, production begins according to the confirmed requirements.

Inspection and Delivery

After the quotation, specifications and purchase order are approved, production begins according to the confirmed requirements.

Quality Built into Every Manufacturing Stage

Quality control begins before production. Our engineers review your drawings, materials, tolerances and inspection requirements so that critical features are understood before manufacturing starts.
