The ventilated cup lid is jointly developed, after customer came to us with the ideas of solving conventional cup lids' problem and the attempt to extend new opportunities by optimizing the design.

CLF's professional R&D team recommends the two-color injection machine for production.

Technically, the temperature of the first-shot material shall be higher than that of the second shot to avoid the second-shot material's overcasting on the first-shot one, that causes materials mix-up and unclear color separation.

However, under this assumption, the mold size will lengthen the production cycle time and a larger injection machine is required. This will lead to an unfavorable situation that customer will afford higher cost in developing new products and markets.

Throughout CLF R&D team's study, the law is broken by injecting TPR in the first-shot and PP in the second. The optimized mold design and production stability are achieved with injection optimization and proper ventilation membrane selection.

Eventually, a cup lid can be made in 8 seconds with the 8-cavity dual-color injection on a rotatory table, with robots' membrane-applying, product removal, stacking and packaging.
