1. Core Structure

Wing Shaped Handle:

• Shape: With a double-wing symmetrical design reminiscent of enchanting butterfly wings, each wing extends a length of 10-25mm and a thickness of 2-4mm, creating a formidable torque lever effect capable of manual torque ranging from 0.5-1.5N · m.

Surface treatment: Enhanced with roll patterns and anti-slip protrusions, ensuring a firm grip and preventing any chance of slippage during usage.

• Threaded Body:

Thread type: Precision-crafted in standard metric/imperial threads (like M6, 1/4-20 UNC) with a universal level precision of 6g.

Thread length: Ranging from 8-30mm, thoughtfully matched to suit specific application scenarios for optimal performance.

• Neck Transition:

• Diameter: Designed to be approximately 0.5-1mm smaller than the thread's largest diameter, effectively preventing handle and substrate interference.

• Strength: Reinforced with a thickened neck design (wall thickness of at least 1.5mm) to withstand the rigors of tightening without compromising its structural integrity.

2. Materials and Craftsmanship

• Substrate Selection:

PA66+GF30%: Offers superior strength with a tensile capability of ≥ 80MPa and impeccable temperature resistance (-40 ºC to 120 ºC), making it ideal for rugged outdoor equipment.

POM (Saigang): Known for its self-lubricating properties (friction coefficient 0.15-0.25) and minimal water absorption (0.2%), perfect for precision instruments.

PP (polypropylene): Cost-effective with a unit price approximately 40% lower than PA66, it is food-grade certified, making it suitable for household appliances.

• Molding Process:

Injection molding: Achieves a seamless one-time molding with tolerance control as precise as ± 0.1mm, ensuring no seams between the thread and handle for a flawless finish.

• Secondary Processing: For superior models, innovative ultrasonic welding with metal inserts, such as stainless steel threaded sleeves, is applied to enhance wear resistance.
