NOTES for Figure 6 & 7: 1. If gate detail does not properly fit the application, contact DME for assistance about gate detail options. 2. Position gate detail within ±0.013mm/.0005in from nominal. 3. The gate diameter can be opened by the customer to suit the application. (The land must be re-machined to the maximum dimension after increasing the gate diameter.) 4. Water lines are required in “A” plate for proper gate cooling. 5. Position water lines as close as possible but not closer than the minimum distance shown to provide a safe steel condition. 6. For faster color changes, remove (“decone”) the resin from the front of each point gate tip prior to changing colors. 7. The minimum “Z” dimension is 13.00 and the maximum “Z” dimension is 115 for point gate and sprue gate tips.
