Industrial Sewing Services
MIL-SPEC contract sewing for military, government, and commercial applications — Westminster, CA
Overview
APPF Inc. provides heavy-duty contract industrial sewing services from our facility in Westminster, CA. From Large Area Maintenance Shelters (LAMS) to military webbing straps, harnesses, and heavy-duty bags, our experienced team delivers precision-sewn products that meet the most demanding MIL-SPEC and commercial specifications.
Our industrial sewing capabilities complement our RF welding services, allowing us to produce complex assemblies that combine sewn and welded components — a capability few contract manufacturers can offer under one roof. We work with nylon, polyester, canvas, Cordura, and specialty technical fabrics using lockstitch, chainstitch, and walking-foot sewing systems engineered for continuous-duty production.
With decades of experience serving military, government, and commercial clients, we understand the importance of quality, consistency, and on-time delivery. Our team is trained to work to MIL-SPEC and commercial standards, and our ITAR registration, Berry Amendment compliance, and CAGE Code (1NLJ3) make us a qualified partner for government programs.
Industrial Sewing at APPF
Industrial sewing uses heavy-duty, continuous-duty machines engineered for production environments — not craft or apparel work. APPF's sewing systems use lockstitch, chainstitch, and walking-foot mechanisms with servo-driven motors, enabling precise stitch control and consistent seam quality across heavy, multi-layer, and coated technical fabrics.
Walking-foot and needle-feed systems are critical for technical fabrics like Cordura, canvas, and urethane-coated nylon — standard drop-feed machines cause seam defects on these materials. APPF's equipment handles the full range of military and industrial technical textiles, from lightweight nylon webbing to heavy multi-layer shelter panels.
Lockstitch
Two-thread interlocking seam — strong, consistent, widely used for structural seams, webbing, and bags.
Chainstitch
Flexible stitch allowing stretch — ideal for shelter panels and applications where material expansion is expected.
Walking Foot / Needle Feed
Essential for heavy, coated, and multi-layer technical fabrics — prevents slippage and seam defects.
Materials & Applications
Materials We Sew
- • Nylon — webbing, straps, harnesses, bags
- • Polyester — structural fabrics, covers, panels
- • Cordura — abrasion-resistant military and tactical gear
- • Canvas — heavy-duty covers, tents, shelters
- • Urethane-coated fabrics — sewn + welded hybrid assemblies
- • Specialty technical textiles — per customer specification
Products & Applications
- • LAMS — Large Area Maintenance Shelter components
- • Military webbing — straps, harnesses, tie-downs
- • Bags & pouches — heavy-duty military and commercial
- • Tents & shelters — structural seams, door assemblies
- • Vehicle covers — truck, aircraft, and equipment covers
- • Hybrid assemblies — sewn + RF-welded under one roof
Key Differentiator
Sewing + RF Welding Under One Roof
Few contract manufacturers can offer both industrial sewing and RF welding in a single facility. APPF does — and this capability is critical for complex assemblies that require both technologies. Inflatable structures with sewn attachment points, tension fabric panels with welded seams and sewn reinforcements, military shelters requiring both airtight welds and structural stitching — APPF handles all of it without splitting your order across multiple vendors.
