HDC CNC Machining

HDC specializes in CNC Machining, Investment Casting, Hot Forging and Metal Fabrication Parts, focusing on custom metal parts

Established in 2009, HDC is a professional manufacturer of various precision CNC machined and metal fabrication parts. With many years of OEM work for our customers, we have gained rich and vast experience in OEM machining and gathered a group of skilled workers and experienced engineers. In 2010, we started to focus on billet CNC machined parts for sports motorcycles. In the years that followed, we keep accumulating knowledge and experience in this field and gradually move forward to an even bigger product range in other motorcycle sectors like ATV, UTV, and Kart parts. We cultivated an excellent customer base through our quality of work, customer service, and passion for what we do. Since 2018， We start to produce trailer parts, including weld-on hinges, trailer couple, trailer ramps, continuous hinges, U-bolts

🧪 720 hours salt spray. That's 30 days. Non-stop.
🌊 Most castings show rust in 48 hours. Ours stayed clean the whole time.
🔬 Right alloy. Dense casting. Clean surface. No porosity for corrosion to start.
✅ Real order. Real test. Real result.
👇 Need castings that survive real environments? Message us.

🔥 Shell firing – we bake ceramic shells at 950–1150°C.
🎯 Two purposes: Sinter the shell to full strength. Burn off any residual wax.
❌ Miss this step? Residual organics gasify at 1500°C during pour – gas porosity in your part.
♨️ Shells go from furnace straight to pouring – red-hot, minimal thermal shock, no cracks.
🏭 2 furnaces running in sync with melting – continuous flow, consistent quality.
👇 Need castings made with real process discipline? Message us.

🔥 Pouring – this is where metal meets shell.
💧 Shell straight from the furnace. Molten metal poured in. Gravity does the rest.
🌡️ Temperature matters. Too hot? Mold erosion. Too cold? Freeze-off.
⏱️ Speed matters too. Fast and steady. No trapped air, no missed sections.
🏭 Melting? We've got 2 vacuum furnaces + 3 medium-frequency ones – flexible for any alloy.
👇 Need castings that fill every corner of your drawing? Message us.

♨️ Dewaxing – wax out, cavity in.
💨 High-pressure steam autoclave + hot water dewaxing tank – two ways to get the wax out.
🔥 0.6–0.8 MPa pressure blast. Why? Wax expands faster than ceramic. No pressure? Shell cracks.
✅ Instant flash-melt. Wax drains clean. No micro-fractures. Perfect cavity every time.
♻️ Melted wax? Collected, filtered, reused – for runners, not your parts.
👇 Need castings with cavities that actually match your drawing? Message us.

🏗️ Before we cast your parts, we build the right tooling.
🔧 CNC. EDM. Aluminum, copper, or tool steel – all to match your drawing.
📐 Shrinkage compensation? Parting line control? We dial it all in before the first wax shot.
💰 Tooling fee? Yes, upfront. But hit your volume target? We refund it.
📦 Need custom castings? We do investment casting molds – and sand casting molds for larger parts too.
👇 Got a drawing? Let's talk parts. Message us.

💉 Wax injection – basically plastic injection molding, but with casting wax.
🌡️ 52-65°C. 1.5-2.5 MPa pressure. Hold time adjusted by wall thickness.
🏭 7 injection machines running. Plus 1 3D printer for quick-turn prototypes when you need them fast.
🔍 After injection? We inspect every pattern – remove parting lines, residue, flashes.
❌ Why? A tiny mark on wax = permanent defect on your metal part.
👇 Need custom castings? Message us.

🕐 Shell drying in progress – and we never skip a layer.
🌡️ 8 to 24 hours per coat. Climate-controlled room at 22-25°C, 50-65% humidity – monitored 24/7.
❌ Rush this? Shell cracks. Or worse – explodes under molten metal.
✅ We wait. Every layer. Every batch.
✨ Why? A strong shell = smooth surface + no leaks + your geometry survives.
👇 Need castings made with patience? Message us.

🛠️ Post-pour. Post-cut. Now finishing.
💥 Shot blasting first – shell residue gone, actual surface revealed for inspection.
🔧 Weld repair? Grinding? Heat treatment? We do what's needed, in-house.
🏭 5 shot blast machines, 2 heat treatment furnaces, 2 sand blasters, 1 straightening press – all under one roof.
✅ Why in-house? Full control from start to finish. No outsourced steps, no compromised quality.
👇 Need castings that are truly finished? Message us.

🕯️ You might wonder why these wax patterns look different.
🌡️ Low-temp for cost efficiency. Medium-temp for stability. Filled, soluble, gating wax – we match it to your part.
♻️ Recycled wax? Yes, we reclaim it. But not for your custom parts – only for gating and runners. Your parts get virgin wax. Every time.
👇 Need the right wax for your parts? Message us.

🔍 Wax pattern finishing – this is where small details matter.
❌ A tiny scratch on the wax? It'll show up on your metal part. Permanently.
✅ We inspect, repair, and clean every pattern – parting lines, residue, flashes – all gone.
✨ Smooth wax = smooth casting. No shortcuts.
👇 Need castings with clean surfaces? Message us.
