Product Description

This hybrid machine combines PUR dotting for breathable softness and silicone tracing for enhanced design and support. Perfect for seamless, comfortable, and stylish bras.

1. Dual-Function Design:
* PUR Dotting: Ensures even adhesive distribution for seamless bonding, providing ultra-softness and breathability.

* Silicone Tracing: Adds elegant patterns and reinforced edges to enhance design appeal and structural support.

2. Superior Comfort & Support:
* The PUR dots create a flexible, lightweight feel without compromising durability.

* Silicone tracing strengthens bra edges for better lift and weight distribution, ideal for supportive lingerie.

3. Customizable Patterns:
* Adjust dotting density and tracing designs to meet specific brand requirements. Create unique bras that stand out in the
market.

4. High Efficiency & Precision:
* Fully automated process reduces labor costs and ensures consistent quality. Perfect for mass production without sacrificing
detail.

5. Wide Application:
* Suitable for seamless bras, sports lingerie, swimwear, and other adhesive-based apparel.

Product Detailed Introduction

Our new generation of seamless bra production equipment is a perfect integration platform for the world's leading PUR dotting technology and silicone tracing technology. It breaks the limitations of single processes and, through intelligent collaborative operation, achieves both structural support and excellent breathability of the product in a single forming process, bringing you unprecedented production flexibility and product competitiveness.

Dot & Line Combination, Complementary Advantages Creating the Ultimate Wearing Experience

Uses high-elasticity liquid silicone to draw the core support structure. Silicone is extremely soft to the touch with excellent stretch recovery (tensile force), providing comfortable and powerful uplift support for the breasts like a "second skin," especially suitable for plus-size and functional bras.

Uses high-performance PUR hot melt adhesive for precise dot spraying. Dot distribution replaces traditional full-layer glue brushing, greatly increasing the breathable space of the fabric, avoiding stuffiness, and providing a dry and comfortable breathable experience.

Design Freedom, One-Step Forming" - Simplified Process, Unleashing Creativity

Designers can freely design any combination of "lines" and "dots" in one software suite, infinitely expanding product diversity.

One-step completion of the application and hot-press curing of both adhesives greatly simplifies the production process, reduces
semi-finished product handling, significantly improves production efficiency, and reduces reliance on labor.

Brands and manufacturers committed to producing mid-to-high-end, high-value-added seamless bras, especially those focusing on plus-size bras, sportswear/leisure lingerie, and high-design products.

Conclusion

This equipment is not just a machine upgrade; it's a revolution in production technology. It allows you to produce top-tier products that combine the soft comfort of silicone with the breathable dryness of PUR in the most economical way. Choosing it means choosing stronger product competitiveness, a broader market, and a more efficient future.

FAQ

Q: Is this hybrid machine more complex and difficult to operate than purchasing two separate machines?

A: On the contrary. Our equipment integrates a unified intelligent control system and operating software. Operators only need to complete the design of "dots" and "lines" and issue production commands in one interface, and the equipment will automatically coordinate the work of the two systems. This is much simpler than operating and managing two separate machines with two different software systems, significantly reducing the operational difficulty and technical requirements for staff.

Q: The maintenance of PUR adhesive is troublesome. How does your equipment solve the problems of carbonization and clogging?

A: This is a top priority in our design. We have adopted multiple patented technologies to address this: Intelligent Short-Flow Path Glue Supply System: Significantly reduces the residence and heating time of adhesive in the pipeline, suppressing carbonization at the source. Quick-Disconnect Modular Nozzles: Should cleaning be required, they can be directly removed and replaced in minutes, minimizing downtime. Precise Temperature Control: Ensures PUR is heated accurately only where needed, preventing excessive degradation. While the PUR part still requires regular maintenance, our design has made it exceptionally simple and fast, with overall maintenance costs much lower than traditional pure PUR equipment.

Q: Compared to traditional brushed glue, is the bonding strength of tracing + dotting sufficient?

A: Absolutely sufficient, even superior. Our process uses a hot press for high-temperature and high-pressure curing (150°C, 20 seconds), enabling both silicone and PUR to form strong bonds with fabric fibers. The silicone lines themselves have excellent stretch and adhesion, providing the main structural bond. At the same time, PUR is renowned for its extremely high initial tack and ultimate bond strength, and its dot structure allows deep penetration into the fabric. The combination creates a dual guarantee of "mechanical anchoring" and "chemical bonding", making it very strong and durable.
