Two-Color Bathroom Mug Plastic Injection Mold

A bathroom tumbler is a glass or cup or mug that is kept in the bathroom for teeth brushing, water scooping or other uses. With the advent of the paper cup and an increased awareness of disease prevention, the modern tumbler is often a decorative accent rather than a useful item.  That’s why two-color cups become popular day by day.

There are many different design of two-color cups.  This kind of two-color mug is widely used at bathroom because of the handle design.  This handle design of two-color cup is not only for saving plastic material, the main advantages are as below:

1. Easy for stacking to save space.

2. Easy for hanging.

3. Easy for mold fabrication.

With regard to mold design, it is unnecessary to have sliders during ejection of handle.  Meanwhile, the mold size will be smaller and mold cost will be lower as well as shorter cycle time.  Meanwhile, the maintenance cost of mold will be lower in future because there won’t have wearing or broken on sliders.

The technical key point of this double-color bathroom mug is parting line of handle and cup top flange.  The first color will be crushed by second color during injection of second color.  Hence, the radian of parting line on first color is very important factor during two-color mould fabrication.

Moreover, the shiny surface of two-color cup is required by consumers which is not only for pleasing to the eyes, but also is not easy for protection of contamination.  Therefore, the high-end polish of double color mould cores and cavities is strongly demanded.
