Precision Tungsten Carbide Needle Holder Inserts with Pyramid Serrations

Our Tungsten Carbide Needle Holder Inserts (Jaw Tips) are engineered to meet the stringent standards of the surgical instrument manufacturing and repair industry. Featuring a precision-engineered 90° cross-hatch pyramid teeth profile, these inserts deliver an exceptional, non-slip grip on delicate suturing needles while extending the service life of high-end medical forceps.

Key Technical Highlights

• 90° Precision Pyramid Teeth: The working surface is meticulously formed with a 90-degree angular tooth profile, providing uniform multi-directional pressure to secure needles tightly without causing structural damage.

• Optimized Pitch Options (0.4mm & 0.5mm):

• 0.4 mm Pitch (Fine): Ideal for smaller, delicate needles used in fine general surgery and micro-procedures (featured on our 15mm and 17mm models).

• 0.5 mm Pitch (Standard): Engineered for general and heavy-duty suturing tasks requiring robust needle retention (featured on our 20mm models).

• Strict Dimensional Tolerances: Designed with a standard thickness of 0.7mm, a 0.2mm edge radius configuration, and precision-engineered top radii (R1.75) to guarantee seamless brazing and flawless fitment onto stainless steel instrument jaws.

• 100% Medical-Grade Tungsten Carbide: Outstanding wear resistance and corrosion proofing, fully capable of withstanding repeated high-temperature autoclave sterilization cycles without losing sharpness.

Standard Size & Specifications

* Note: Customized dimensions, specific blank geometries, and tailored cobalt content are available upon request to match your proprietary drawings.

Brazing & Assembly Support

The back surface of our carbide inserts is treated with a specialized precision grinding process. This enhances the surface roughness required for superior wetting during silver soldering or vacuum brazing, eliminating the risk of insert delamination or cracking at the joints during heavy clinical use.

Why Source From Us?

• Complete Traceability: Every production batch is backed by comprehensive metallurgical analysis and hardness testing report.

• Zero Defect Guarantee: 100% optical inspection under magnification to ensure consistent pyramid teeth geometry and zero missing tips.

• Global OEM Supplier: Based in the center of China’s cemented carbide industry, providing high-volume stability and cost-efficient lead times for international medical instrument brands.

Түгээмэл асуултууд:

А1: Та үйлдвэр эсвэл худалдааны компани мөн үү?
Бид 12 жилийн үйлдвэрлэлийн туршлагатай үйлдвэр юм.

Q2: Танай үйлдвэр хаана байрладаг вэ?
Бид вольфрамын карбидын суурь болох Хунань мужийн Жужоу хотод байрладаг.

Q3: Үнэ өрсөлдөх чадвартай юу?
Бид өөрийн гэсэн үйлдвэртэй. Хүчтэй үйлдвэрлэл, түгээлтийн системийн ачаар бид хэрэглэгчиддээ хамгийн өрсөлдөхүйц үнийг санал болгохоо амлаж байна.

Q4: Бүтээгдэхүүн нь өндөр чанартай юу?
Тиймээ. Бүх бүтээгдэхүүнийг бөөнөөр нь үйлдвэрлэхээс өмнө туршиж үзэх бөгөөд тээвэрлэхээс өмнө чанарын шаардлага хангасан бүтээгдэхүүнийг баталгаажуулахын тулд физик шинж чанар, хэлбэр, хүлцлийг шалгах болно.
