This Bi-Material Mask Mould has 2 cavities of inner part and 2 cavities of outer part. Mould injection system is 1st shot PP hot runner open gate and 2nd shot TPE hot runner valve gate. The cores and cavities are made by STAVAX 420 steel.
The materials of the Bi-Material mask is PP and TPE. The PP material is firm that the shape of the mask. TPE material is soft and elastic, can be fitted to the mask, more comfortable to wear. The two-color masks not only make the masks colourful, but also suitable for people to wear for a long time.
The Bi-Material Masks are in close contact with the skin on people’s faces, which means that the Bi-Material Mask Injection Mould needs to be especially precise and do not allow for flash and rough ejection marks or anything that may cause uncomfortable to the people.
Due to we make the injection inside, the gate, cooling ejection and ejection systems need special careful design, which greatly increases the difficulty of the mould. In addition, the operating steps of the mould are different. When the second colour injection is finished, the mould opens, and the cylinder glides, then the slider and the product depart, and finally the ejector pin ejects.
To make such difficult moulds, you must choose an excellent mould maker. YUEYI Mould, a professional two-colour injection mould maker. Over the past 30 years, YUEYI Mould has mastered the art and science of twice-injection moulding. We have the design, engineering and in-house tooling capabilities you need to streamline your project from conception to production.
