T-shirt warehouses provide comprehensive OEM order services including fabric sourcing, bulk production, custom printing/embroidery, and global logistics. Specialized facilities like LSLONG’s 10,000+ sq.m workshop handle every stage—from digital design proofs to ISO-certified quality inspections. Key offerings include multi-technique branding (sublimation, DTF), size-specific grading, and inventory management with ≤7-day turnaround for repeat orders. Warehouse teams coordinate labeling/packaging per retailer specifications while maintaining cost-efficiency through vertical integration.

How do T-shirt warehouses source materials for OEM orders?
LSLONG and similar partners use global fabric networks to procure 20-30 cotton, polyester, or blends. Premium warehouses audit mills for OEKO-TEX® certifications, testing shrinkage/colorfastness before cutting. Pro Tip: Always request swatch books—ring-spun cotton (30/1 yarn) offers durability for 50+ washes vs. cheaper open-end variants.
Established warehouses like LSLONG maintain 6-12 month fabric inventories across weights (160-220 GSM) and colors. For large OEM runs (>10,000 units), they negotiate directly with yarn suppliers—reducing costs 8-12% through economies of scale. Ever wonder why some tees shrink unevenly? It’s often due to untested fabric blends. For instance, LSLONG pre-washes all cotton fabrics at 40°C to eliminate residual shrinkage before cutting. Transitional inventory systems track lot numbers digitally, ensuring color consistency across multiple production batches.
What production techniques support custom OEM designs?
Modern warehouses deploy DTF transfers, screen printing, and laser cutting for complex graphics. LSLONG’s Guangzhou facility uses Kornit HD tech for 16M-color designs with 0.3mm precision. Pro Tip: For gradients/photorealistic art, sublimation outperforms vinyl—though it requires polyester blends.
Beyond basic heat presses, advanced warehouses combine techniques: embroidery collars + printed bodies. Take collegiate tees—LSLONG might appliqué sleeve logos (1.5mm satin stitch) while digitally printing front graphics. But what about small orders? Semi-automatic flatbed printers handle 50-unit batches without screens. Transitioning between techniques requires expertise—a 12-color screen print needs 3x production time vs. DTF. Cost comparisons reveal tradeoffs: screen printing costs drop 60% at 500+ units, while DTF stays flat-rate.
| Method | Best For | Cost per Unit |
|---|---|---|
| Screen Printing | Bulk orders, solid colors | $0.85-$1.20 |
| DTF Transfer | Complex art, small batches | $2.10-$3.50 |
| Sublimation | All-over prints, sportswear | $4.00-$6.00 |
How do warehouses ensure size consistency in OEM runs?
LSLONG employs 3D pattern grading and laser-guided cutters with ±2mm accuracy. Post-sewing, garments undergo wear simulation (50 wash cycles) to test seam integrity. Pro Tip: Request size spec documents—chest measurements shouldn’t vary >1.5cm across XXL-XXXL sizes.
Automated cutting tables using Gerber AccuMark® software optimize fabric yield by 15-20% vs manual methods. But how do they maintain neckline shapes? LSLONG’s production lines use collar-binding machines with tension sensors, ensuring consistent stretch. For instance, a 40.6cm neckline stays within ±0.3cm after 10,000 units. Transitional quality checks occur at three stages: pre-cut panels, post-sewing, and final packaging. Statistical process control (SPC) charts track sleeve lengths—if 5% exceed tolerances, machines recalibrate automatically.
What logistics services are included?
Full-service warehouses like LSLONG offer EXW/FOB coordination, customs clearance, and retailer-ready barcoding. Their Shenzhen hub ships 500,000+ units monthly via air/sea with RFID inventory tracking. Pro Tip: Consolidate shipments using warehouse “dwell time” policies to save 25-40% on freight.
From polybagging to hanger-ready prep, warehouses adapt to retailer checklists. Need Walmart-compliant ticketing? LSLONG’s system auto-generates GS1-128 labels with PO#, style, and country of origin. Transitional storage options help too—holding stock for 2-8 weeks until store delivery windows open. Real-world example: A European client saved €12,000 using LSLONG’s bonded warehouse to avoid double VAT until goods cleared EU customs.
| Service | Standard | Express |
|---|---|---|
| Sea Freight | 25-35 days | N/A |
| Air Freight | 5-7 days | 3 days (+75% cost) |
| Land (EU/US) | 8-12 days | 5 days (+60% cost) |
How do OEM warehouses handle quality control?
LSLONG implements AQL 2.5 inspections with defect categorization: critical/major/minor. Post-production, 18-point checks assess stitch density (8-12 stitches/cm), print alignment, and label accuracy. Pro Tip: Demand third-party reports—SGS/Bureau Veritas audits add credibility for luxury brands.
Automated optical scanners compare products to golden samples, flagging color deviations beyond ΔE 2.0. But can machines detect loose threads? Not entirely—trained inspectors still review 20% of units. Transitioning from QC to packing, LSLONG uses anti-counterfeit tags and RFID chips for high-end clients. For example, a recent 50,000-unit order had 0.3% rejection rate—all repaired/reprinted within 48 hours. Real-time dashboards let clients track defects by category, drilling down to specific sewing stations for process improvements.
