Engineered Casting Solutions for U.S. Enterprise Programs
We deliver production‑grade casting for small‑ to mid‑size parts where design freedom, part consolidation, and total cost matter. Compared with sheet‑metal fabrication, casting enables near‑net‑shape geometries—integrating ribs, bosses, channels, and complex features—reducing welds, fasteners, and secondary machining at target volumes.
Process Capability
- Lost foam casting for complex internal/externals and tight integration
- Custom tooling (made‑to‑order molds) optimized for fast‑moving SKUs and repeatability
What You Can Expect
- Per‑print manufacturing with DFM support and controlled tolerances
- Strength assured: mechanical properties validated to spec (tensile, hardness, leak/pressure as required)
- Materials: aluminum, iron, stainless steel (typical alloys)
- Experience: core engineering team with 20+ years in foundry processes and application engineering
When Casting Beats Sheet Metal
- Complex geometries and angles
- Part count and weld reduction
- Better unit economics at defined production volumes
Engagement
- Rapid sample patterns, scalable production, and documentation on request (material certs, test reports)
Precision Machining
As a senior engineer, my job is to turn your drawings into production‑ready parts with repeatable quality, controlled risk, and total cost clarity. Our precision machining service combines robust process control with flexible capabilities—so complex geometries, tight tolerances, and fast lead times can coexist.
- CNC milling & turning (3/4/5‑axis), mill‑turn, grinding, wire EDM, drilling/tapping
- Materials: aluminum, carbon/alloy steel, stainless steel, brass, copper, selected engineering plastics
- Fixturing & tooling engineered for stability, throughput, and cost
Typical Tolerances & Finishes (Machining Standards)
Actual achievable tolerances depend on geometry, material, volume, and process route. The values below reflect common U.S. machine‑shop practice.

- Runout (rotational features): 0.001–0.002" (0.025–0.05 mm) with proper fixturing
- Surface finish (Ra): 125–63 µin (3.2–1.6 µm) standard; 32–16 µin (0.8–0.4 µm) fine; ≤8 µin (≤0.2 µm) via grinding/lapping
Heat Treatment
We treat heat treatment as a controlled special process—engineered for repeatable mechanical properties and stable dimensions.
For each material and geometry, we build a data‑driven process window (preheats, austenitizing temperature & soak, quench design, temper cycles) to achieve the required balance of hardness, strength, toughness, and dimensional stability. Distortion and cracking risks are addressed up front through fixturing, staged preheats, controlled cooling, and quench agitation management.
Core Services
- Hardening & Tempering (oil/water/polymer quench, single or multiple tempers)
- Annealing & Normalizing (structure refinement, machinability improvement)
- Stress Relieving (residual stress reduction after machining or welding)
- Process Validation & Lot Documentation (hardness tests, traceability, data packs)
Extended processes via qualified partners: carburizing/carbonitriding, nitriding, induction hardening, solution treatment & aging for PH stainless (on request).
Process Control & Quality
- Closed‑loop temperature control with documented ramp/soak/cool profiles
- Routine instrument calibration and uniformity checks
- Quench consistency (bath temperature, concentration, and agitation control)
- Lot‑based verification: hardness (Rockwell/HV) and optional metallography
- Full traceability: furnace ID, sensor IDs, process traveler, and inspection records
What Clients Receive
- Repeatable properties and tighter dimensional stability across lots
- A complete data pack: process curves, hardness reports, and traceability
- A production approach consistent from prototype to volume manufacturing
Engineered Post‑Weld Galvanizing — Electro‑Galvanizing & Hot‑Dip
After welding, we apply zinc coatings to significantly improve the corrosion resistance of painted parts and extend service life. A zinc layer provides both barrier protection and sacrificial (cathodic) protection. When combined with paint (a “duplex” system), the coating system performs exceptionally well in demanding environments.
Option 1 — Electro‑Galvanizing (EG)
Electro‑galvanizing uses an electrolytic process to deposit zinc at controlled, uniform thickness. It is ideal for tight tolerances, fine threads, and assemblies that need a smooth finish for paint.
- Typical coating mass: 40–60 g/m²
Converted: 0.131–0.197 oz/ft²
Approx. thickness: ~5.6–8.4 µm - Why choose EG: Uniform appearance, excellent paint adhesion, minimal impact on dimensions, good for indoor or moderate outdoor service when painted.
Option 2 — Hot‑Dip Galvanizing (HDG)
Hot‑dip galvanizing immerses the welded assembly in molten zinc (~450 °C), creating a metallurgical bond with robust intermetallic layers beneath a pure zinc topcoat—ideal for harsh outdoor exposures.
- Typical coating mass: ≥ 260 g/m²
Converted: ≥ 0.852 oz/ft²
Approx. thickness: ≥ 36.4 µm - Why choose HDG: Heavy‑duty protection, excellent edge coverage, superior durability for structural and outdoor applications; paint over HDG further boosts long‑term performance.
Applied After Welding — What We Control
- Surface prep: Removal of scale/spatter, degreasing, pickling or blasting; activation for EG, fluxing for HDG.
- Weld‑ready design: Vent and drain holes for hollow sections (HDG), masking of threads/bearing surfaces when required.
- Dimensional care: Fixturing and process controls to limit distortion; selective coating strategies for functional surfaces.
- Paint system integration: Compatible pretreatments and topcoats to reach your target durability.
Standards & Quality Assurance
- Electro‑Galvanizing: per ASTM B633 (electrodeposited zinc on steel), service classes SC1–SC4 as specified.
- Hot‑Dip Galvanizing: per ASTM A123/A153 or ISO 1461 for fabricated steel products and hardware.
- Verification: Magnetic thickness and coating mass checks, adhesion/continuity inspection, full lot traceability.
How Does Galvanizing Work?
Powder Coating
What we do. After welding and fabrication, we apply electrostatic powder coatings to deliver a durable barrier with excellent paint adhesion and long‑term corrosion resistance. Using AkzoNobel (Interpon) powders, we match RAL/Pantone or custom colors, and offer finishes from matte, satin, high‑gloss to textured/metallic per your design.
Adhesion & Thickness (Verified)
- Adhesion: Target ASTM D3359 cross‑hatch rating 4B–5B (substrate and pretreatment dependent).
- Typical film build: 60–120 µm (≈ 2.36–4.72 mils) for exterior‑grade systems; heavier builds available for edge coverage and impact resistance.
- Cure control: Metal temperature and dwell set per AkzoNobel data sheets (e.g., 180–200 °C / 356–392 °F for 10–20 min), logged for traceability.
Pre‑Spray Surface Preparation (Process Control)
- Mechanical cleaning (de‑spatter, deburr; optional abrasive blasting to spec).
- Degreasing/alkaline wash and multi‑stage rinse.
- Conversion coating: iron/zinc phosphate for carbon steel; chromate‑free (zirconium/permanganate) for aluminum, as specified.
- DI rinse & dry, followed by masking of functional surfaces and verified grounding.
- Electrostatic application with controlled kV/µA, film build measurement, and oven cure per powder spec.
Lines & Capacity
- Powered conveyor line — max part envelope length 6.0 m × height 2.1 m
(≈ 19.69 ft × 6.89 ft) — ideal for continuous throughput and repeatability. - Enclosed batch oven line — max part envelope length 12.0 m × height 2.4 m
(≈ 39.37 ft × 7.87 ft) — suited for larger/heavier weldments and extended cure profiles.
Why it matters
- Post‑weld application ensures edges, heat‑affected zones, and weld seams are properly sealed.
- Documented process: pretreatment logs, cure charts, and film‑build records accompany each lot.
- Color you specify: AkzoNobel formulations matched to your brand standard or environment.
