Patent Technology | The Craftsmanship Behind 237 Core Patents
Thirty years dedicated to one thing: perfecting cutting tables and rewinding machines
Since its establishment in 1999, White has consistently focused on the research and manufacturing of automatic cutting tables, tape rewinding machines, and slitting equipment. We have not blindly expanded our product line; instead, we chose a more challenging path—continuously refining our limited range of products, building technological barriers with patents, and defining industry standards through precision.
Three decades of focus have resulted in 237 core patents. These patents are not mere certificates on the wall, but tangible improvements in details, performance breakthroughs, and enhancements in user experience on every piece of equipment.
Our Patents Address Your Real Pain Points
▍ ±0.03mm Micron-Level Positioning Accuracy
For high-value materials like electronic tape and optical films, a 1mm deviation could mean the entire roll is wasted. White's R&D team has improved cutting table positioning accuracy to ±0.03mm throughhigh-precision ball screw drive patents and imported servo motor closed-loop control, achieving a minimum cutting width of 0.5mm. This technology has been applied to high-end models such as the F400 and F330S, helping customers increase material utilization rates to over 98%.
▍ Patent Silencer Technology – Noise Reduction by 70%
The high-frequency noise in tape slitting workshops has long been a persistent issue in the industry. White's mechanical engineers developedan integrated silencer device patent after hundreds of acoustic simulations and structural optimizations, reducing operational noise by 70% without affecting slitting speed (260m/min). This not only improves the working environment for employees but also helps customers easily pass occupational health and safety certifications.
▍ Non-Stop Automatic Shaft Change System – Efficiency Increase of 20%
Traditional rewinding machines require downtime for changing rolls, involving unloading shafts, threading tubes, and restarting, resulting in lost production time. White'sfully automatic flip shaft patent technology allows for non-stop shaft changes, automatic labeling, and automatic cutting, reducing roll change time from several minutes to just seconds. For example, the HT-809 fully automatic rewinding machine can complete over 1000 rolls of tape per hour, achieving an overall efficiency increase of over 20%.
▍ One-Click Parameter Switching – Setup Time Reduced by 50%
Tape factories often need to frequently change materials (BOPP, washi tape, PET, double-sided tape, etc.), requiring reconfiguration of tension, speed, and cutter position each time. White'sintelligent parameter memory system patent can store up to 100 sets of material formulas, allowing operators to simply click on the material name on the PAD screen, automatically adjusting all parameters and reducing setup time from half an hour to just 3 minutes.
▍ Easy-to-Clean Safety Protection Structure
During tape processing, glue and dust can easily adhere to the surface of the equipment, affecting hygiene and potentially causing malfunctions. White has obtaineda patent for an easy-to-clean appearance design, featuring rounded transitions, no exposed screws, and removable protective panels, combined with food-grade coatings, reducing cleaning and maintenance time by 40%. Additionally, multiple safety interlocks and emergency stop systems comply with CE standards, preventing personal injury from accidental operations.
From Patents to Products, From Products to Value
The 237 patents are not for decoration but to answer the three most practical questions from our customers:
Is the accuracy sufficient? → ±0.03mm positioning accuracy, micron-level processing capability.
Is the efficiency high? → Non-stop shaft change, one-click parameter switching, efficiency increase of 20%.
Is it safe? → Noise reduction, easy cleaning, CE safety certification, ensuring peace of mind in production.
Continuous Innovation, Because Customers Keep Presenting New Challenges
White's R&D team consists of over 150 engineers, investing 8% of annual sales into new technology development. We do not work in isolation but delve into customer sites worldwide—from tape factories in Vietnam to electronic material workshops in South Korea—listening to real feedback, transforming pain points into patents, and integrating those patents into products.
