3x4 Bra Hook and Eye Closure Manufacturer

Industrial Applications of 3x4 Bra Hook and Eye Closures

The 3x4 bra hook and eye closure is designed for garments that need wider back fastening, stronger hold and multiple adjustment positions. It is used in full cup bras, plus-size bras, shapewear, corsets and supportive lingerie programs.

Where 3x4 Construction Is Used

Four adjustment positions give the wearer a wider fitting range, while the three-hook structure supports stronger tension distribution across the back panel.

Custom Manufacturing Capabilities

HS ALF produces 3x4 closures as a factory-direct B2B supplier. Tape width, hook spacing, fabric, metal finish, color, packaging and labeling can be adapted to customer specifications.

Development from Customer Samples

Production can be prepared according to approved samples, technical drawings, Pantone codes, fabric references or finished garment requirements.

Technical Specifications and Product Structure

The 3x4 structure combines three hook rows with four adjustment positions. This format is selected when a wider closure area and more stable support are required.

Dimensional Stability

Stable tape width, accurate hook alignment and clean edge finishing help garment factories reduce sewing variation and maintain repeatable assembly.

Tape Material Options

Tape can be produced with 100% polyamide or 100% cotton according to product requirements. Polyamide supports durability and color stability, while cotton offers a softer and more natural touch.

Material Selection

The suitable tape material is selected according to garment type, sewing method, comfort target, washing expectations and the market segment of the final product.

Metal Options and Skin-Friendly Finishes

Nickel-free, stainless steel and gold-plated metal options are available depending on comfort, durability and appearance requirements.

Metal Surface Control

Surface smoothness, coating consistency, component position and fastening function are checked during production and final inspection.

Color Matching: Standard, Pantone and Customer Samples

HS ALF offers more than 60 standard factory colors. For custom programs, colors can be matched to Pantone references, fabric samples, elastic bands or customer-approved master samples.

Batch-to-Batch Consistency

Approved color references can be archived for repeat orders, helping customers maintain visual consistency across seasonal production.

Manufacturing Process and Factory Workflow

The workflow includes material approval, tape preparation, hook and eye assembly, cutting, cleaning, inspection and packing.

In-Process Control

Intermediate checks help identify alignment, color or sewing issues before final inspection and support consistent production quality.

Quality Control and Performance Checks

Quality control covers tape material, hook alignment, sewing quality, color accuracy, surface appearance, packaging and lot identification.

Additional Checks on Request

Needle detector compatibility, wash resistance checks and pull-strength evaluation can be discussed according to buyer requirements.
