Precision Multi-Cavity Pipette Tips Mold Insert for Medical Injection Mold Tooling
Product Overview
This precision multi-cavity pipette tips mold insert is designed for high-volume medical injection molding applications. Manufactured from high-grade stainless mold steels such as STAVAX, 1.2083, or SS420, this insert plate ensures excellent corrosion resistance, high wear resistance, and ultra-precise cavity geometry.
The insert integrates a high-density cavity array specifically engineered for the production of laboratory pipette tips, enabling stable mass production with consistent dimensional accuracy. It is widely used in medical consumables molds, where surface finish, micro-precision, and durability are critical.
As a custom precision mold component manufacturer, we produce fully customized mold inserts based on customer drawings or mold design requirements, ensuring perfect compatibility with existing injection mold systems.
Product Description
The pipette tips mold insert plate is a critical functional component in medical injection molds. It forms the core structure responsible for shaping the internal geometry of pipette tips used in laboratory testing, diagnostics, and life science research.
Because pipette tips require extremely thin walls and precise taper geometry, the mold insert must achieve high-precision machining, excellent surface polish, and consistent cavity alignment.
Our inserts are manufactured using advanced CNC machining, precision EDM, and high-accuracy grinding processes. Each cavity is carefully machined to ensure uniform tip dimensions and smooth demolding performance.
To meet the strict requirements of the medical industry, materials such as STAVAX or 1.2083 stainless mold steel are commonly used due to their excellent corrosion resistance and suitability for high-polish mold surfaces.

Why Precision Matters for Pipette Tips Mold Inserts
In the production of laboratory pipette tips, even a small dimensional deviation can affect liquid measurement accuracy and automation compatibility.
Consistent pipette tip geometry
Accurate cavity machining guarantees uniform tip shape and taper angle.
Stable high-volume production
Multi-cavity molds must maintain dimensional consistency across all cavities.
Smooth demolding performance
High surface polish reduces friction and prevents plastic sticking.
Extended mold life
High-quality mold steels provide excellent wear resistance and corrosion protection.
For manufacturers producing medical consumables, precision inserts directly impact product quality, yield rate, and production efficiency.
