The above information is not to be construed as a license or a recommendation to infringe on any patents. Typical properties are for natural,
unpigmented resins unless otherwise stated.
Actual processing conditions will depend on machine size, mold design, material residence time, and shot size. The settings
shown should serve as a guide to achieve the necessary stock temperatures for stable processing and good product quality. Stock melt
temperatures taken with a hand pyrometer is the best guide for selection of optimum operating conditions.
