Frequently Asked Questions: How to assess the actual production capacity of a custom T-shirt factory?
Assessing factory capacity requires focusing on four core indicators: factory area, equipment configuration, number of skilled workers, and supply chain coordination capabilities. A qualified custom factory should have a standard workshop of several thousand square meters, equipped with modern fully automated sewing and finishing equipment. In addition, if the factory can provide integrated services from fabric development, plate making to printing and embroidery, the delivery cycle will be greatly shortened.
From Fabric to Craftsmanship: Core Considerations for Choosing a Professional Custom T-Shirt Company
Materials and Cut
High-quality garments begin with the fabric. As a meticulous custom t-shirt company, we conduct rigorous weight and shrinkage tests on every piece of fabric. Below is a comparison of key fabric parameters commonly used in our bulk customization:
| Applicable Weight Range | Product Features | Recommended Application Scenarios | |
| 100% Combed Cotton | 160g – 260g | Breathable and sweat-absorbent, excellent skin-friendliness, high luster | High-end brand basic T-shirts, children’s wear |
| Heavyweight Cotton | 280g – 320g | Crisp and structured, durable and washable, with a retro feel | Streetwear, oversized T-shirts |
| Cotton-Polyester Blend (CVC/TC Blend) | 300g – 420g | Strong wrinkle resistance, not easily deformed, excellent warmth | Autumn/Winter heavyweight sweatshirts, hoodie sets |
| Cotton Spandex | 190g – 240g | Excellent elasticity, slim fit without being tight, good resilience | Sports fashion T-shirts, women’s custom clothing |
D/3D Visual Upgrade
We offer comprehensive visual craftsmanship customization services to make your brand logo and designs highly recognizable:
- High-Precision Embroidery: Utilizing imported embroidery machines, the dense and even stitches easily achieve a three-dimensional texture for your brand logo.
- 3D Embossing: Unique 3D raised textures are embossed onto the fabric using high-temperature molds, creating a subtly luxurious visual effect.
- Diverse Printing: Covering environmentally friendly water-based printing, plastisol printing, digital direct-to-garment (DTG), and heat transfer printing, ensuring high color fidelity.
Sizing and Pattern Making
We have established a comprehensive international standard sizing library, including US Size, EU Size, and Asian Size.
Furthermore, our pattern makers can perform 1:1 pattern making and fine-tuning based on paper patterns or reference garments provided by buyers. We pay particular attention to details such as double-needle reinforcement at the neckline and anti-deformation webbing on the shoulder straps, ensuring that the garment remains crisp and sturdy even after multiple washes.
Core Knowledge Q&A: What are the differences between OEM and ODM models in garment customization?
A: OEM (Original Equipment Manufacturing) refers to the buyer providing complete technical drawings, fabric specifications, and design source files, with the factory only responsible for pure contract manufacturing. ODM (Original Design Manufacturing), on the other hand, involves the factory not only handling production but also participating in early-stage style design, fabric development, and pattern adjustments. Heyisenlin supports both OEM and ODM services and can provide flexible cooperation models based on your level of expertise.
Flexible, one-stop, fully customized services for worry-free purchasing.

Comprehensive Customization: From main labels, care labels, hang tags to custom packaging bags, everything can incorporate your corporate culture and logo.
End-to-End Supply Chain Support
We understand that buyers’ biggest concern when sourcing internationally is the potential for process disruption; therefore, we provide transparent, end-to-end services.
- Requirements Communication: A professional project manager will provide one-on-one support to clarify fabric, craftsmanship, sizing, and budget requirements.
- Fast Sampling: We have an independent sampling team that can provide accurate pre-production samples (PP Samples) within 3-7 days.
- Bulk Production Scheduling: Once the sample garment is confirmed and a deposit is received, standardized assembly line production begins immediately, with real-time progress updates.
- Strict QC: Establish a full-inspection quality control position to inspect each piece for loose threads, size deviations, and stains, preventing defective products from leaving the factory.
Core Knowledge Q&A: How to ensure the QC pass rate when wholesaling garments in large quantities?
A: Ensuring the pass rate requires establishing three lines of quality control: pre-production, production, and post-production. First, pre-production fabrics must undergo shrinkage and colorfastness testing. Second, during production, first-piece confirmation and inspection are necessary to promptly correct stitching issues. Finally, finished products must undergo full or random inspection according to AQL 2.5 or higher international standards, focusing on verifying garment dimensions, stains, and packaging specifications.
