2K Injection Mold for Medical Oxygen Mask

Leave a comment

This medical oxygen mask is a dual-component molded part made of PP rigid plastic and TPE soft material, manufactured by 2K two-color injection mold.
PP material forms the main frame to maintain structural rigidity and shape stability, while soft TPE is applied on facial contact rim to achieve comfortable wearing and good sealing performance. Two materials are overmolded in one cycle with reliable adhesion, preventing peeling and separation during application.

Medical plastic components require strict control on appearance, dimensional tolerance and surface profile. With rich experience in precision 2K mold manufacturing, we optimize cavity layout, gating sequence, ejection and venting system to overcome typical defects such as short shot, air bubble and warpage on thin-wall curved parts.
Finished masks feature smooth surface, uniform TPE thickness and ergonomic curve for proper sealing, suitable for mass production in medical industry.

Yueyi Mold is capable of full-cycle development for two-color molds, including design, machining and mold trial. We accept custom precision 2K injection molds for medical consumables and protective products. Customers can send 3D drawings for technical evaluation and mold proposal.

Production of Two-Color Toothbrush Mold (PP+TPE Material)

The two color toothbrush mold is produced using a rotating shaft  design within the injection mold structure.

This mold is used on angle injection molding machines, requiring precise alignment and rotation.

The toothbrush is made from PP and TPE.

PP provides rigidity and durability, while TPE adds a soft, comfortable grip for the user.

The core and cavity are used from high-quality 1.2316 steel, offering excellent corrosion resistance and polishability.

Although the structural design is more challenging, attention to detail ensures optimal performance.

The runner system often employs a full hot runner with multiple valve gates

to ensure precise material distribution and improve surface finish.

Proper venting and cooling designs are essential to prevent defects and ensure consistent cycle times.

At YUEYI Mould, we focus on translating customer needs into optimal production solutions.

Every new mold we design undergoes rigorous trial molding and inspection to guarantee quality and functionality.

lid mould

We manufacture a single-color mold for producing three different lid sizes in one cycle.

The cavity layout is 2+2+2, This design improves production efficiency while keeping tooling costs reasonable.

The core and cavity are machined from 1.2738HH steel.

It ensures the mold runs reliably for long production runs with minimal maintenance.

We use a 6 tips valve gate. it also prevents stringing and drooling, which keeps the molding process clean and stable.

At YUEYI, we focus on practical, high-quality molds.
