FIVE KEY PRODUCTION PROCESSES
1. Door Handle Production Process
[Critical Control 1]: Piece-by-piece inspection after polishing.
[Critical Control 2]: Inspection under standard light.
1. Melting and casting: High-quality ZAMAK/aluminum alloy.
2. Mechanical processing: Automatic thread tapping.
3. Fine polishing: Machine grinding combined with manual.
4. Multi-layer coating: Reinforced electroplating for protection.
5.Assembly and test: Manual installation of springs and return test.
6. Branded packaging: Client's individual boxes.
2. Lock Body Production Process
[Control]: 100% check of the deadbolt's smooth operation.
1. Stamping: High-precision stamping from cold-rolled steel St3.
2.Component test: Checking springs and deadbolts for fatigue.
3. Manual assembly: High-precision manual fitting of mechanisms.
4. Packaging: Branded packaging for protection during logistics.
3. Cylinder Production Process
[Test]: Simulation of use with the original key.
1. Precision milling: High accuracy of copper drilling.
2.Manual lubrication: Lubrication for low temperatures down to -40°C.
3. Manual assembly: High-precision manual pin placement.
4. Packaging: Individual branded box.
4. Armor Plate Production Process
[Control]: Checking the electroplated layer for scratches.
1. Forging/Casting: Forming a thickened protective layer.
2. Coating: High-quality electroplating instead of PVD.
3. Assembly: Manual installation of all fasteners.
4. Packaging: Individual branded packaging.
5. New Product Development Process
FAI: Destructive testing of the first product.
1. Profile analysis: Checking Backset and mounting locations.
2. Drawing approval: Fixing all technical parameters.
3. 3D prototype: Making a sample for fitting on the door.
4. Mold development: Manufacture of precision tooling.
5. Mass production: Launch of the series and packaging.
Technical Regulations and OEM/ODM FAQ
In this section, we answer 20 engineering questions so you can be confident in every stage of BBDHOME production.
CATEGORY: PROCESSES AND QUALITY
[Q1] How is electroplating quality controlled?
[A1] We conduct a 72-hour ISO 9227 test and visually inspect each part manually for micro-pores before assembly.
[Q2] Why is manual assembly of locks better?
[A2] An experienced master feels the spring tension, which eliminates the risk of mechanism jamming in the future.
[Q3] Do you use secondary zinc?
[A3] No, BBDHOME uses only primary ZAMAK alloys to ensure the strength and durability of the coating.
[Q4] How is spring reliability tested?
[A4] Each batch of springs passes a metal fatigue test: more than 200,000 actuation cycles.
[Q5] What does the FAI process include?
[A5] This is a complete measurement of the first product from a new mold and destructive tests to check strength.
CATEGORY: DEVELOPMENT AND MOLDS
[Q6] What is the timeline for new mold development?
[A6] Usually 35-45 days: from drawing and 3D model approval to obtaining the first castings for tests.
[Q7] What is the lifespan of your molds?
[A7] Our steel molds are designed for 300,000-500,000 high-pressure casting cycles.
[Q8] Can design changes be made at the 3D stage?
[A8] Yes, this is the most effective way to reduce TCO before expensive metal work begins.
[Q9] Is it compatible with Euro Profile?
[A9] Yes, our locks are designed to the DIN standard, which allows the use of any Euro-standard cylinders.
[Q10] How is silent operation ensured?
[A10] We use a PVC Silent Latch and precision fitting of the internal parts of the lock body.
