In-Depth Leather Production Process at TANNARK
At TANNARK, our leather goods production integrates traditional craftsmanship with modern technology to deliver high-quality, consistent, and scalable products. Here’s a detailed look into how we turn raw leather into premium jackets, gloves, biker suits, and more:
Design & Product

Sketching & Conceptualization
- Our creative team begins with hand-drawn sketches or digital concepts provided by clients.
- We analyze trends, client specifications, and functional needs to finalize the product design.
CAD (Computer-Aided Design) Processing
- Designs are transferred into CAD software (e.g., AutoCAD, Gerber, Optitex) for precision pattern-making.
- CAD allows:
- Exact measurement adjustments
- Virtual fitting and modifications
- Pattern grading for different sizes
- Efficient marker making to minimize leather waste
DIY (Design Your Idea) / Prototyping
- Using CAD patterns, we create sample prototypes or DIY models to test fit, comfort, and style.
- Prototypes undergo internal review and client feedback for adjustments before bulk production.

Leather Selection & Inspection
- Raw hides are inspected for defects, thickness, grain quality, and color consistency.
- Only hides meeting strict quality criteria proceed to cutting.
Cutting Process
Manual Cutting Tools
- For small batches or delicate pieces, expert cutters use hand-held rotary knives, leather shears, and scalpels for precision.
Machine-Assisted Cutting
- For bulk orders, we use clicker presses with metal dies to cut multiple layers accurately and quickly.
- Automatic cutting machines (like Gerber or Lectra systems) use CAD files to cut complex shapes with laser or blade precision, reducing waste and increasing speed.
Skiving & Edge Preparation
Edges of leather pieces are skived (thinned) using manual skiving knives or electric skivers to ensure smooth seams and reduce bulk.
- This step is crucial for comfort, especially on collars, cuffs, and gloves.
Assembly & Stitching
Stitching Machines
- We use a range of industrial sewing machines suited for heavy leather:
- Cylinder-bed machines for tubular or round parts (like gloves).
- Flat-bed machines for larger flat surfaces (jackets, pants).
- Post-bed machines for precise detail work.
- Machines include brands like Consew, Juki, and Pegasus, renowned for reliability and strength.
Hand Stitching
- Certain parts requiring finesse, like decorative topstitching or bespoke repairs, are done by skilled artisans using hand-sewing techniques.
Hardware & Finishing
- Hardware components (zippers, buckles, snaps) are installed using specialized pressing machines and manual tools to ensure durability.
- We use YKK zippers and rust-proof metal hardware preferred in European markets.
Quality Control
- Post-assembly, each product undergoes a multi-stage QC process:
- Stitching strength and seam integrity tests
- Color and finish inspection under natural light
- Fit and comfort evaluation (samples tested on mannequins or models)
- Packaging inspection to prevent damage during transit
Packing & Shipping
Finished goods are packed in protective, eco-friendly materials.
- Bulk orders are palletized or boxed according to client instructions for safe export.
