The World of Brick-Built Car Collecting
Adult collectors build vehicle models for display and stress relief. The demographic includes IT professionals, engineers, and designers — builders who demand high part counts, functional steering, and detailed engine bays. Complex models require focus and precision that reward patience.
The community shares modifications and custom designs online. Builders post photos of completed models, exchange instruction modifications, and trade spare parts. Collecting scale models integrates genuine engineering principles: gear ratios, suspension systems, and drivetrain mechanics. Explore our full range of premium vehicle sets at MOREBYBOURN.

Understand Mould King and Alternative Bricks
Premium alternative bricks use high-grade ABS plastic with a stud tolerance matching official brands at ±0.01 mm. This ensures high clutch power and full compatibility — you can mix these parts directly with your existing collection without structural gaps or misalignment.
Mould King specializes in massive, motorized, and highly detailed models. Their vehicle sets often exceed 3,000 pieces and include carbon-fiber axles, high-torque motors, and pneumatic components. The price is typically 40–70% lower than official brand equivalents while using the same food-contact-grade BPA-free resin.

Sorting numbered bags before assembly is the single most important step for 3,000+ piece builds
Expert Tip
Always buy from retailers that offer a missing-pieces guarantee. At MOREBYBOURN, we replace missing or broken pieces free of charge on every order — no questions asked.
How to Find an Old Mould King Car
Locating a retired or classic Mould King vehicle requires specific search strategies. Some models enter production retirement and the secondary market takes over. Use the set number rather than the model name when searching — set numbers return exact matches on every marketplace.
Search by Set Number
Use the exact set number rather than the model name. Set numbers guarantee exact matches on secondary market platforms.
Check Builder Forums
Dedicated alternative brick communities frequently list unbuilt sets. Members are transparent about completeness and condition.
Verify Before Buying
Ask for photos of sealed bags, the instruction manual condition, and whether the sticker sheet is intact and unused.
Buy Current Classics
For guaranteed completeness, buy current classic-style models from MOREBYBOURN. Every order ships with a missing-pieces guarantee.
Assemble Your Vintage-Style Brick Car
Building a 3,000-piece model requires a systematic approach. Follow the four phases below for a smooth, frustration-free assembly. Each phase builds on the last — rushing ahead will cause rework.
Chassis & Frame
- Clear a large table with space for the manual, chassis, and sorted parts.
- Open Bag 1 only. Sort contents by color and size into labelled trays.
- Connect Technic beams securely — test gear alignments immediately.
- If a gear grinds now, diagnose and fix before moving forward.
Tip: Use an LED desk lamp. Black and dark grey pins look identical in low light.
Drivetrain & Electronics
- Install motors and the battery box during this phase — not later.
- Test all electronics before sealing them inside the model body.
- Route cables away from moving gears to prevent binding.
- Secure the battery compartment so it remains accessible after completion.
Tip: A quick motor test now saves hours of disassembly later.
Interior Details
- Build seats, dashboard, and steering column as sub-assemblies first.
- Connect the steering wheel to the front axle rack before enclosing.
- Fit the interior sub-assembly into the chassis as a single unit.
- Check steering movement is smooth through the full lock range.
Tip: Test steering lock-to-lock before closing the floor plate.
Bodywork & Stickers
- Attach exterior panels starting from the rear and working forward.
- Apply stickers using tweezers — never fingers — for precise alignment.
- Press all panels firmly inward to ensure zero gaps between body sections.
- Perform a final function test: steering, motor response, opening panels.
Tip: Warm the sticker sheet slightly with a desk lamp before applying — it reduces air bubbles.
Do
- Sort every numbered bag before opening the next.
- Keep a brick separator tool within reach at all times.
- Test gears and motors before sealing the chassis.
- Apply stickers with tweezers for precise alignment.
Don't
- Open all bags at once — you will lose small pieces.
- Force connections — recheck the step if resistance is felt.
- Use compressed air to clean bricks — it dislodges small parts.
- Seal the electronics before testing motor response.
Maintain and Display Your Collection
A finished Mould King vehicle is a display piece that represents dozens of hours of work. Proper maintenance protects that investment. ABS plastic degrades under UV exposure and extreme temperature — both easily avoided.

A UV-protective acrylic case is the single best investment for long-term ABS preservation
Dust Protection
- Use a dust-proof acrylic display case.
- Clean exposed models monthly with a soft makeup brush.
- Never use compressed air — use a hand-pumped silicone blower.
UV & Heat Control
- Keep models out of direct sunlight — UV turns white bricks yellow.
- Store in a climate-controlled room — heat warps long Technic beams.
- Choose display cases with UV-filtering acrylic for premium builds.
Storage & Spares
- Store extra parts in labelled zip-lock bags by part number.
- Keep the instruction manual flat — never roll or fold it.
- Store the original box flat to preserve resale value.
