Process of making screwdrivers
Blade:
Raw material: The raw materials for screwdrivers are very basic
Cutting: The wire is first drawn to the required diameter.
Degreasing & drying
High performance alloy steel
Chrome plated blade for corrosion resistance
Black tip for precision tip. Higher accuracy
1st Injection:
Colouring: The next step is to make the handle of the screwdriver
The handles are usually made of cellulose acetate
Polypropylene
Easy to choose the right tip with color-coded handle
2nd Injection
These steel bars then undergo machining to form the head
The other end of the steel bar is then stamped
Hardening and Annealing The steel bars are then given heat treatment. This process involves baking the wire at a temperature about 732 degrees for 12 hours to obtain the correct tensile strength in the metal.
Surface treatment: A surface treatment is given for protection
Black oxidation: Followed by oxidation process
The injection process is done by a extruder machine
High impact polypropylene
Provides optimum robustness and strength
3rd Injection: The screwdrivers are now almost ready
The screwdrivers are placed in a printing machine
Soft touch elastomer with rigid surface for better grip patented manufacturing system for the symbol on the domed end
Thermal Printing: The screwdrivers are placed in a printing machine
Thermoforming Inlays:
This machine prepares the packaging molds
The screwdrivers are then kept in the molds
Finish
Quality control: QC tests are performed: Iso, IEC 60900
Ergonomic Design:
3 Component handle for maximum comfort and force transmission
Black tip for precision tip, higher Accuracy
Cylindrical shaft with small diameter tighten and loosen screws quickly and easily
Optimal length on the handle neck
Only rounded shapes, no pressure points
Thermo printed marking of tip size
1. Make Table of entities and activities for the production process.
2. Create Flowchart of the production process built
