HDC CNC Machining

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

🏗️ 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.

💉 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.

🌲 Wax tree assembly – this is where small parts become a batch.
🔥 Why trees? Smart gating design = better material yield, fewer defects.
📏 Spacing matters. Too tight? Slurry can't reach. Too loose? Waste.
🧊 Directional solidification? We design gates by wall thickness – thick to thin, no shrinkage cavities.
🧠 Every tree layout is custom – our engineers run casting simulations for your part geometry.
👇 Got small parts that need casting? Let's talk tree design. Message us.

🧲 Stainless steel + magnet = still stainless.
❌ Thought all stainless is non-magnetic? That's a common one.
🔬 316 is austenitic. Non-magnetic by nature. But cold working? That can shift the structure. A little martensite forms. A little magnetism shows up.
✅ Doesn't change the alloy. Doesn't change the corrosion resistance.
📄 Need proof? Material test report comes with every custom casting we ship.
👇Got a drawing? Let's talk. Message us.

🏭 Three machines. One goal: clean castings.
❌ Leave sand and oxide on the surface? That's asking for rejected parts.
✅ Knockout + shot blast in one pass. Then two more blasters for good measure.
👇 Want castings that actually look like metal? Message us.

🌀 Custom turbine housing – wax pattern vs finished part.
🔥 Porosity kills turbos. Cracks kill housings. We cast neither.
✈️ CNC machining afterward? Yes. Safe blade clearance, every time.
📄 Certified high-temp materials. No substitutions.
👇 OEM/ODM welcome. Low MOQ? Also fine. Message us.
