Turnkey Custom Manufacturing Solutions

Stop juggling multiple vendors. We integrate High-Pressure Die Casting, Precision CNC Machining, and Final Assembly into a single, streamlined workflow.

Simplify Your Supply Chain

Why Sourcing is Often a Headache

The “Vendor Blame Game”

When defects occur, the caster blames the machinist, and the machinist blames the raw material. You are left absorbing the cost.

Bolang Solution: Single Point of Accountability. We manage the entire lifecycle.

Logistics Nightmares

Moving parts from Factory A to Factory B adds weeks to lead times and increases shipping damage risks.

Bolang Solution: Internal transfer. Zero freight costs between processes. 30% faster turnaround.

Inventory Bloat

Managing minimum order quantities (MOQs) from three different suppliers ties up your cash flow.

Bolang Solution: JIT (Just-In-Time) delivery of finished, kitted assemblies ready for your line.

From Drawing to Retail-Ready Product

Unlike traditional job shops that only perform one step, Bolang operates as your manufacturing partner. Our “Mission Protocol” ensures we deliver solutions that fit directly into your final product line.


  • Integrated Quality Control:
    CMM data correlates casting density with machining tolerances directly on our factory floor.
  • Surface Finish Management:
    We oversee anodising, powder coating, and plating through trusted partners, inspected by our team.
  • Dual-Shore Security:
    Utilise our Malaysia facility to mitigate tariff risks for global distribution to US and EU markets.

Success Story: Supply Chain Consolidation

The Challenge

A UK-based LED lighting manufacturer was sourcing raw castings from China, machining them in the UK, and painting them at a third facility. Logistics costs consumed 18% of the product margin, and lead times averaged 14 weeks.

The Bolang Solution

We took over the entire project as a Turnkey Solution. We cast the housing (ADC12), performed precision CNC machining, applied the powder coating in-house, and kitted the gaskets.

The Result

35% Cost Reduction
6 Weeks Lead Time Cut
0 Freight Between Processes

Value-Added Services (Beyond Machining)

Industrial Ultrasonic Cleaning for automotive parts

Technical Cleaning

Industrial ultrasonic cleaning lines ensure parts are free of coolant, chips, and oils, meeting strict cleanliness standards for automotive and medical sectors.

Visual sorting and quality inspection

100% Visual Sorting

For cosmetic critical parts, we deploy visual inspection lines to check for surface defects, scratches, or coating inconsistencies before packing.

Custom packaging solutions for export

FAQ: Managing Your Custom Project

Do you offer VMI (Vendor Managed Inventory) or JIT delivery?

Yes. For long-term partners, we can hold safety stock in our warehouse (in China or Malaysia) and ship based on your weekly forecast. This helps you reduce local warehousing costs while ensuring Just-In-Time (JIT) delivery.

How do you protect my Intellectual Property (IP)?

We take IP strictly. We sign a legally binding NDA (Non-Disclosure Agreement) before receiving any drawings. Your designs are stored on a secure, restricted-access server and are never shared with third parties without written consent.

What if there is a quality issue with a sub-component (e.g., plating)?

We take full responsibility. As the prime contractor, Bolang is your single point of accountability. If a plated part fails our incoming inspection, we handle the rework or replacement with the plating partner. You never have to chase sub-suppliers.
