MOLD COOLING High-Temperature Insulator Sheets and Locating Rings High-Temperature Insulator Sheets (HTIS) for Plastics Molds and Die-Cast Dies
MOLD COOLING Pre-Machined Insulator Sheets
Pre-Machined Insulator Sheets for Plastics Molds Standard Features Insulator Sheets are designed to fit most standard mold base sizes (see table lower right).
•
Asbestos-free material
•
High compression strength
• Machinable with high-speed cutting tools DME High-Temperature Insulator Sheets are used on molds and dies between the top clamping plate and the stationary platen, and between the bottom of the ejector housing and the movable platen. The thermal insulating properties of this unique asbestos-free, glass-reinforced polymer composite inhibit heat transfer from the mold to the platen, or from the platen to the mold (depending on the application), which helps conserve energy and prolong machine life. These sheets have excellent non-deformation characteristics and a compressive strength,* which is higher than asbestos and mica materials. Compression molded for high impact strength, they are supplied micro-finished top and bottom, parallel within ±.002.
•
Pre-machining includes: • Assembly screw hole clearance • Locating ring clearance hole • Insulator sheet mounting holes
•
2 thicknesses of Insulator Sheets ( 1 ⁄
4 " or
1 ⁄
2 ")
• 16 " shorter on all sides to prevent sheet damage during mold handling • Custom Insulator Sheets available • Asbestos-free material • High compression strength • Use with locating rings 6541 and 6544 • Can be used on both top and bottom of mold bases Specifically designed to be 1 ⁄
Locating Rings (6541, 6544) for use with Insulator Sheets These thicker Locating Rings are used with Insulator Sheets 1 ⁄ 4 and 1 ⁄ 2 thick. They extend beyond the Insulator Sheet far enough to ensure more than 5 ⁄ 16 pilot engagement with the locating hole in the machine platen.
