CNC Machining for OEMs and Manufacturers That Need Reliable Production Support

We work with OEMs, equipment manufacturers, and product companies that rely on outsourced CNC machining for ongoing production.

Our customers value consistent quality, responsive communication, and a manufacturing partner who can reliably manage the manufacturing side — from machining and secondary processes to inspection and repeat production.

We work with your team to resolve manufacturing details and help keep production moving with consistent quality from order to order.

One Reliable Source for CNC Production Parts

Mastro helps manage the manufacturing side of your CNC production parts, not just the machining itself. We coordinate production through one dependable source, with a focus on quality, responsive communication, and consistency across repeat orders.

Responsive Communication

Direct communication, timely production updates, and quick follow-up.

Manufacturing Coordination

CNC machining, heat treatment, surface finishing, and other secondary processes coordinated through one point of contact to reduce handoff issues and simplify overseas sourcing.

Consistent Repeat Production

Inspection and production control focused on maintaining consistent quality from one order to the next.

Production Support Capabilities

Supporting processes and quality control to help maintain consistent quality across repeat production runs.

Inspection and Quality Control

ISO 9001 quality control with routine in-process checks and final inspection, using appropriate measuring tools and inspection equipment. Inspection records and material certificates are available.

Heat Treatment

We support a range of heat-treatment and hardening processes, including vacuum heat treatment, nitriding, induction hardening, laser hardening, and QPQ, to improve hardness, wear resistance, and durability for production parts.

Automatic Production

Automated loading helps run batch production more efficiently, reduce manual handling, and keep lead times and costs under better control.

Surface Finishing

We support anodizing, hard anodizing, plating, black oxide, sandblasting, polishing, tumbling, and other surface finishes for production parts.

Taiwan & China ｜ ISO 9001 Certified ｜ Precision CNC Production

Materials We Machine

We machine a wide range of metals and engineering plastics for CNC turned, milled, and multi-axis production parts.

Aluminum

Lightweight and versatile, widely used for precision machined parts with anodizing and other surface finishing options.

Stainless Steel

Widely used for precision machined parts requiring strength, corrosion resistance, and durability.

Steel and Tool Steel

Carbon, alloy, and tool steels for production parts requiring strength, wear resistance, hardness, or post-machining heat treatment.

Brass

Excellent machinability, good corrosion and wear resistance, and useful electrical conductivity for precision turned parts, fittings, connectors, valves, and repeat-production components.

Titanium

High strength-to-weight ratio and excellent corrosion resistance for precision machined parts used in demanding, lightweight applications.

Engineering Plastic

We specialize in machining POM, PTFE, nylon, PE, and other engineering plastics for precision components, with material options selected based on friction, chemical resistance, insulation, and weight requirements.

High-Precision Plastic Machining: Simple Parts Are Not Always Easy

Plastic parts often look simple on a drawing. Compared with stainless steel, aluminum, or brass components, many plastic parts do not look very complicated. The material is softer, the shape may be simple, and the part may only have a few critical dimensions. But in real CNC machining, plastic is not always easy. At Mastro Machine Shop, we have machined many precision plastic components for mechanical assemblies, industrial equipment, optical products, automation systems, and

Outsourcing Machining to China or Taiwan: How to Pick the Right Shop (Without Getting Fooled by “Big Factory” Photos)

When we talk to customers who outsource machining to China or Taiwan, the most common question is always the same: “There are so many suppliers… how do I choose the right one?” Here’s my honest take: factory size is not the key. Not how many machines they have. Not how many employees. Not how fancy their inspection room looks on a website. The real key is matching your part to the shop’s core strength. In machining, every shop has a different “sweet spot.” Before you send out
