Custom Manufacturing, Built Around Your Drawings
Made-to-Order Production from Your Specifications
Every project starts with your drawing, sample, or technical specification. You define the geometry, material, and dimensional requirements. Our engineers then review the design for manufacturability and confirm the tolerance plan before production begins.
Tolerances protect fit and function. They define the acceptable range for each dimension, and you should state them clearly on your drawing.
Machining tolerances refer to the allowable variation in dimensions, shape, and position of a machined part from the intended design specifications. Tolerances are specified to ensure that the machined parts fit together, function properly, and meet the required performance standards.
When your drawing leaves tolerances open, we apply ISO 2768 general tolerances by default.
| Deviation Range (in.) | f (fine) | m (medium) | c (coarse) |
|---|---|---|---|
| 0.019–0.118 | ±0.0019 | ±0.0039 | ±0.0078 |
| 0.236–1.181 | ±0.0039 | ±0.0078 | ±0.0196 |
| 1.181–4.724 | ±0.0059 | ±0.0118 | ±0.0314 |
Typical targets include ±0.005 in. for standard machining, ±0.002 in. for precision work, and ±0.0005 in. for reamed holes. We also accept GD&T callouts such as true position, flatness, and concentricity per ASME Y14.5.
From Rapid Prototyping to Volume Runs
You can validate a design before you commit to tooling. Metal 3D printing and CNC machining produce functional prototypes in days. You test the fit, adjust the drawing, and approve the final revision.
The same process then scales to volume. Casting and forging tools take over for larger batches, and machining brings critical features to final tolerance. Order quantities stay flexible, from a single prototype to mass production.
One Partner for Casting, Forging, Machining, and 3D Printing
Splitting a project across vendors creates handoffs, and handoffs create delays. Keeping every process under one roof gives you a single continuous production flow with consistent inspection at each stage.
| Advantage | What It Means for You |
|---|---|
| Single point of contact | Clear ownership from casting to finishing |
| Fewer supplier handoffs | Less rework and fewer inconsistencies |
| Full-lifecycle control | Predictable quality and better visibility |
| Centralized accountability | Aligned inspection across the full process |
Our English-speaking team coordinates each step, so your specifications travel intact from drawing to delivered part.
Capabilities, Materials, and Quality Control
Your part moves through several process stages before it ships. Each stage has its own equipment, its own material behavior, and its own inspection points. This section shows you what happens at each stage and how we keep the output matched to your drawing.
Core Processes and Equipment
Our 26,200 m² plant in Jimo, Qingdao houses the full process chain under one roof. You get casting, forging, sheet metal fabrication, precision machining, metal 3D printing, and surface finishing from a single production base.
Casting covers three routes. Die casting shapes aluminum and zinc components at high pressure and fast cycle times, which suits high-volume lightweight parts. Precision investment casting uses silicasol molding to deliver tight tolerances and smooth surfaces directly from the mold. Sand casting handles large structural components in QT450 ductile iron, a grade that absorbs shock and vibration in heavy machinery bases. Forging refines the grain structure of the metal and aligns grain flow along your part’s stress lines, which raises fatigue resistance in load-bearing parts.
Precision machining brings critical features to final tolerance. Our equipment supports 5-axis CNC milling for complex geometries in a single setup, CNC turning and composite machining for symmetrical parts, EDM for hard metals, and drilling and tapping for fastening features. Sheet metal fabrication adds laser cutting, CNC bending and spinning, stretching and stamping, and structural welding for enclosures and frames.
Metal 3D printing handles what traditional processes cannot. We print titanium and nickel-based high-temperature alloys with complex internal channels and topological structures. You gain weight reduction without losing mechanical strength, and you gain internal flow geometry that casting cannot produce.
Equipment performance matters to your delivery date. We track machine utilization, overall equipment effectiveness (OEE), scrap rate, and downtime as core production metrics. Utilization compares actual running time to total available production time, and top shops target roughly 75%–85% to maximize throughput without burnout. OEE combines availability, performance, and quality to reveal hidden capacity. These metrics drive our scheduling decisions and your quoted lead times.
| KPI | What It Measures |
|---|---|
| Quality (PPM) | Defects per 1,000,000 parts made and shipped |
| On-Time Delivery | Percentage of parts meeting the agreed ship date |
| Machine Utilization | Percentage of available machine hours actually used |
| Overall Equipment Effectiveness (OEE) | Availability × Performance × Quality |
| Cost of Poor Quality | External quality issues plus internal scrap and rework |
| Preventative Maintenance | Percentage of on-time maintenance performed |
Material Options and Surface Finishes
Material choice shapes your part’s strength, weight, corrosion resistance, and cost. We machine and cast a broad range of metals and engineering plastics, and we help you match the grade to the application.
The most common machining materials break down into seven families:
- Aluminum alloys (6061, 7075, 2024)
- Stainless steel (303, 304, 316, 17-4 PH)
- Brass and copper
- Titanium (Grade 2, Grade 5)
- Tool steels and hardened alloys
- Engineering plastics (Delrin, PEEK, nylon, polycarbonate)
- Composites (carbon fiber, fiberglass)
Each family fits specific applications. Automotive work relies on CNC machining for engine parts, transmission systems, and chassis components. Aerospace work uses aluminum, titanium, and composites for turbine blades and structural elements that must stay light and strong.
| Material | Key Properties | Typical Application |
|---|---|---|
| Aluminum (6061, 7075) | Lightweight, strong, highly machinable; 7075 ranks among the strongest alloys | Automotive and aerospace parts; 7075 used where strength is critical |
| Steel (mild, stainless, tool) | High strength and durability; stainless offers corrosion resistance | Mild steel in automotive; tool steel for cutting and shaping tools |
| Titanium | High strength-to-weight ratio, corrosion resistance, withstands extreme temperatures | Aerospace and other high-stress applications |
| Carbon fiber composites | Exceptional strength-to-weight ratio | Aerospace, automotive, and sporting goods |
| Fiberglass | Glass fibers in a resin matrix | Automotive parts and industrial uses |
Surface finishing protects the part and improves its appearance. Anodizing creates a protective oxide layer on aluminum and resists wear and oxidation. Powder coating applies a thick polymer finish that stands up to impact and chemical exposure. Electroplating and Dacromet coating add advanced corrosion resistance for salt spray and marine environments. Tell us the operating environment, and we recommend the finish that extends your part’s service life.
Inspection, Testing, and Certifications
Quality control starts before the first chip cuts. We review your drawing, confirm the tolerance plan, and define the acceptance criteria for every critical feature. Dimensions never get measured against the exact nominal value. Each design carries a stated tolerance, and inspection verifies that parts fall inside that band.
We apply a 10:1 measurement capability rule. Measuring equipment should be ten times more accurate than the tolerance being verified. A 0.0001 in. tolerance therefore calls for equipment accuracy near 0.00001 in. All inspection tools are calibrated on a regular schedule against standards traceable to NIST.
Our inspection workflow follows four steps:
- Define specifications and acceptance criteria from your drawings and CAD models, with priority on critical-to-quality features tied to fit, function, and safety.
- Calibrate and validate every measurement tool against a traceable standard before use.
- Measure the part with the right workflow, using hand tools for simple dimensions and CMMs with datum alignment and stable fixturing for tight-tolerance features.
- Record every result with nominal value, actual value, tolerance band, and pass/fail status, linked to part number, revision, lot, and inspection date.
| Procedure | Purpose | Key Methods |
|---|---|---|
| First Article Inspection (FAI) | Verify conformance to drawings before full production | Standardized documentation forming part of the quality record |
| In-Process Inspection | Catch dimensional drift before scrap accumulates | Operator checks after setups; SPC charts |
| Dimensional Measurement | Confirm accuracy matching or exceeding tolerances | CMMs (±0.0001″–±0.0005″), optical systems, laser scanners, micrometers, calipers |
| Surface Finish Inspection | Ensure roughness meets functional requirements | Contact and optical profilometers (Ra, Rz, Rmax); visual inspection |
| Material Verification | Confirm mechanical properties and chemistry | Hardness testing (Rockwell, Brinell, Vickers); spectroscopy (XRF, OES) |
| Non-Destructive Testing (NDT) | Detect internal defects without damaging parts | Ultrasonic testing; radiographic inspection (X-ray/gamma) |
We back this workflow with third-party certifications. Our quality system holds IATF 16949 automotive certification and RoHS environmental compliance. Components meet Class 150/300 international pressure rating standards and ASME B16.11 where applicable. Every order ships with 100% dimensional inspection, spectral material validation reports, and non-destructive testing reports covering penetrant testing, radiographic testing, and pressure testing.
Certification requirements vary by destination industry. ISO 9001 serves as the baseline for general industrial parts such as machine components, brackets, enclosures, and fittings. IATF 16949 applies when parts are destined for automotive applications. AS9100 applies when parts are destined for aerospace applications. Share your end-use industry at the quoting stage, and we confirm the certification path your project needs.
Industries Served and How to Start Your Project
Industrial Applications and Part Types
Your industry shapes the parts we build. Automotive work covers gaskets, seals, fasteners, insulation, and plastics such as Delrin and Noryl, often cut by waterjet or laser. Aerospace parts include engine components, structural brackets, housings, shafts, and fasteners in titanium, aluminum, stainless steel, and superalloys. Medical devices, renewable energy systems, and heavy equipment each bring their own part families and tolerance demands.
A Step-by-Step Project Workflow
You send a CAD model and a PDF drawing. We export the CAD as a STEP file for CAM processing, log the part name, number, material, priority, and version, and attach both files to your order entry. Once you approve the plan, production starts. When the part passes inspection, we mark it delivered and ship it with full documentation.
