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. T he 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. P osition water lines as close as possible but not closer than the minimum distance shown to provide a safe steel condition. 6. F or faster color changes, remove (“decone”) the resin from the front of each point gate tip prior to changing colors. 7. T he minimum “Z” dimension is 13.00 and the maximum “Z” dimension is 115 for point gate and sprue gate tips.
