Opening: Factory Direct Sales, Upholding Quality with Craftsmanship

As a footwear manufacturing entity rooted in Rui'an, Kuanghong Footwear's core confidence in the factory direct sales model stems from its meticulous control over every production process. From raw material selection to finished product delivery, three classic processes—cold cement, injection molding, and vulcanization—work in tandem with the POD customization model, making "Made in Kuanghong" a synonym for quality.

I. Cold Cement Process: The Quality Cornerstone of 80% Footwear

As the most widely used technology in the footwear industry (accounting for over 80%), the cold cement process balances precision and efficiency in Kuanghong's workshops:

  • Refined Procedures: From insole nailing and lasting shaping to upper edge roughening, each step is operated to millimeter-level standards. Imported polyurethane adhesives are used, undergoing a closed-loop process of "gluing - activation - pressing - cold setting" to ensure firm bonding between the upper and sole.
  • Quality Control Focus: The original "72-hour room temperature curing test" simulates extreme environments to detect adhesion, keeping the delamination rate below 0.1%. Environmentally friendly glue has passed SGS certification, balancing durability and ecological responsibility.
  • Application Scenarios: Mainstream categories such as leather shoes and sports shoes, excelling in seamless bonding of complex uppers and soles while ensuring flexibility and support.

II. Injection Molding Process: Efficiency Revolution in the Automated Era

Kuanghong has introduced a fully automated injection molding production line, realizing integrated manufacturing from raw materials to finished products:

  • Core Principle: Thermoplastic polyurethane (TPU) and other materials are melted at high temperatures and precisely injected into molds to form an integrated structure with the upper. The entire process—feeding, metering, and mold clamping—is automated, with an error of no more than 0.02mm.
  • Quality Advantages: The sole has uniform density, with impact resistance 40% higher than traditional processes. An automatic detection system monitors injection pressure in real time to eliminate defects such as bubbles and material shortages.
  • Flexible Adaptation: Covers multiple categories including leather shoes, cloth shoes, and plastic shoes, especially suitable for standardized quality control in mass production.

III. Vulcanization Process: Symbiosis of Retro Texture and Durability

Breaking the prejudice that vulcanization is "low-grade," Kuanghong reshapes this classic technology with imported equipment:

  • Upgraded Procedures: After bonding raw rubber sheets with the upper, the product is placed in a precision vulcanization tank for treatment at 150℃ and 3MPa pressure, enabling full cross-linking of rubber molecules.
  • Performance Leap: The finished product's folding resistance exceeds the national standard by 3 times, and the wear resistance index reaches 1200 revolutions per millimeter, making it the preferred process for canvas shoes and outdoor rubber shoes.
  • Triple Quality Inspection: Rubber sheet purity, bonding strength, and finished product weather resistance are tested before and after vulcanization, ensuring each pair can withstand long-term outdoor use.

IV. Upcoming POD Customization: Personalized Manufacturing on Demand

Adapting to the trend of personalized consumption, Kuanghong will soon launch POD (Print on Demand) footwear customization services, realizing "one-piece order, zero-inventory smart manufacturing":

  • Style Selection: Covers specialized shoe bases such as casual shoes and board shoes.
  • Design: Supports pattern upload and text editing, with 300DPI high-definition printing guarantee.
  • Production: Printing starts within 72 hours of order confirmation, using environmentally friendly ink penetration technology.
  • Customization Advantages: Whether for corporate logo customization, personal creative designs, or rapid implementation of trending patterns, it balances personalization and quality, completely solving the pain points of traditional customization—"high minimum order quantity and long lead time."

Conclusion: Craftsmanship as the Guideline, Quality as the Soul

From the precise bonding of cold cement to the durability of vulcanization, from the efficiency of automated injection molding to the flexibility of POD customization—Kuanghong Footwear leverages the short-chain advantage of factory direct sales to fully release the quality potential of each process. Every pair of shoes leaving the factory is a dual response to "craftsmanship manufacturing + personalized needs."
