This is Supplier Spotlight #17 in DEWIN's ongoing factory documentation series. Every factory in our network is physically visited by our on-ground team, photographed, and scored against a 50-point Dolphin Audit framework before being listed for international buyers. No anonymous listings. No unverified claims.
Today's factory: Hitech Mould Company Limited — a Vietnam-based aluminum die casting manufacturer running CNC milling, CNC lathe finishing, and a conveyor belt system for automated semi-finished product flow. Band saw MH-350DM (×2) verified on-site for precision aluminum billet preparation.

Factory Overview: Hitech Mould Company Limited
Hitech Mould is an integrated aluminum die casting and CNC machining factory in Vietnam. Their process capability covers the full production sequence: aluminum billet is cut to charge weight on the band saw, cast on die casting equipment to near-net-shape, then moved via conveyor to CNC milling and CNC lathe stations for post-cast precision machining.
This end-to-end capability under one roof is a significant advantage for international buyers. Many die casting programs require post-cast machining of critical bores, threads, and mating surfaces. Sourcing from a factory that handles both casting and machining eliminates the multi-vendor coordination that drives lead time and quality risk in offshore supply chains.
The Band Saw Story: Why Billet Preparation Is a Quality Indicator
One of the less-discussed upstream process controls in aluminum die casting is billet preparation. Before a billet can be loaded into a die casting machine, it must be cut to the correct charge weight. The method used for this cut is a visible quality indicator that DEWIN auditors specifically document.
At Hitech Mould, our auditors confirmed two Band Saw MH-350DM machines used for billet cutting. A precision band saw with a consistent cutting stop delivers billets to a tight weight tolerance — typically ±1–2g per billet at this machine class. This translates to consistent shot weights during casting, which reduces porosity, incomplete fills, and dimensional scatter in the finished casting.
By contrast, factories relying on angle grinders or manual hack-saws for billet prep produce inconsistent charge weights — a root cause of casting defects that is often traced back only after expensive mould trials or customer returns.
| Billet Prep Method | Charge Weight Tolerance | Casting Consistency | Buyer Implication |
|---|---|---|---|
| Band Saw MH-350DM ✓ (Hitech Mould) | ±1–2g per billet | High — consistent fill, low porosity | Supports FAI dimensional repeatability |
| Angle Grinder | ±5–10g per billet | Moderate — shot variation risk | Higher re-melt scrap rate |
| Manual hack-saw | ±15–20g per billet | Low — porosity and flash risk | Dimensional scatter, incomplete fill defects |
Charge weight tolerance is an upstream process control indicator. Ranges reflect typical industry practice, not Hitech Mould-specific measured data.
Conveyor Belt Flow: Lean Manufacturing in Practice
DEWIN auditors documented a conveyor belt system for transporting semi-finished products within the Hitech Mould facility. In the context of a die casting + CNC machining operation, this is a meaningful lean manufacturing signal.
Manual part handling between die casting and machining stations is a source of damage, batching delay, and FIFO breakdown. A conveyor system enforces ordered, sequential flow: each casting moves from the die casting station along the production line to trimming, then to CNC stations in the order it was produced. This maintains first-in-first-out traceability and reduces work-in-process inventory pile-up.
On the 50-point Dolphin Audit, Pillar 1 (Facility & Safety) and Pillar 3 (Quality Systems) both capture evidence of production flow management. A flow-based layout — supported by physical infrastructure like conveyors — scores higher than a disorganized floor with parts piled in bins between stations.
50-Point Dolphin Audit: What We Found at Hitech Mould
Every DEWIN supplier undergoes a 50-point physical audit before being listed. Here's a summary of the Dolphin Audit findings at Hitech Mould — specific to what international buyers need to know:
| Dolphin Audit Pillar | Evidence Documented | Buyer Relevance |
|---|---|---|
| 1. Facility & Safety | Secured gate, organized workshop, conveyor-based flow between stations | Flow layout = lower WIP damage + FIFO traceability |
| 2. Equipment & Capacity | Band Saw MH-350DM ×2, CNC milling machine, CNC lathe, die casting equipment | Full billet-to-finished-part capability under one roof |
| 3. Quality Systems | Caliper QC station confirmed on-site; in-process dimensional checks | In-line dimensional verification; supports dimensional inspection records |
| 4. Workforce & Management | Dedicated operator stations per machine; on-site process supervision | Stable operator assignment → consistent process parameters on repeat orders |
| 5. Export Compliance | Vietnam-registered manufacturer; VCCI Form B COO eligibility confirmed | FTA eligibility for CPTPP, EVFTA, RCEP, UKVFTA market access |

Frequently Asked Questions
What processes does Hitech Mould offer under one roof?
Hitech Mould offers aluminum die casting, CNC milling (post-cast), CNC lathe turning (post-cast), and band saw billet preparation — all within the same Vietnam facility. This integrated capability covers most aluminum housing and machined casting programs without multi-vendor subcontracting.
What is the DEWIN Dolphin Audit and how does it differ from ISO certification?
ISO certification is a document-based third-party audit of a factory's quality management system. The Dolphin Audit is a physical, on-site 50-point inspection by DEWIN's own team that verifies actual equipment, facility condition, operator practices, and export compliance. Many Vietnam factories lack ISO certification but operate with excellent practical quality systems — the Dolphin Audit captures that reality.
Which markets can source from Hitech Mould with FTA benefits?
Vietnam's FTA network covers buyers in the US (VCCI Form B for Section 301 exemption), EU (EVFTA EUR.1), UK (UKVFTA), Japan, Australia, Canada (CPTPP Form D), and ASEAN/RCEP partners. DEWIN manages the relevant COO documentation for each destination market.
Can Hitech Mould supply CMM dimensional reports for FAI/PPAP?
Hitech Mould has caliper-based in-line QC capability. For programs requiring full CMM-based FAI or PPAP documentation packages, DEWIN can arrange third-party CMM inspection at a partner metrology facility in Vietnam. Discuss your PPAP level requirements at RFQ stage.
