Section 7 - Optimizing Performance

Since weld depth affects the joint strength and the amount of flash generated, it is important to design the weld joint properly to meet both requirements simultaneously. The incorporation of flash trap features is recommended to produce acceptable appearance without compromising strength.

Hold

During the hold phase, vertical press travel initially brings the molten parts closer together (dynamic hold) and then allows the molten material to solidify (static hold). Amourphous plastics will normally take longer to solidify than semicrystalline plastics. The dynamic hold distance is typically a small value compared to the weld distance. An approximate staring point for initial application setup is 10% of weld distance. The static hold time can vary depending on the size of the part, but is usually in the 1-3 second range.

Part Size

Machine model selection will mostly depend on the weld diameter of the parts. Refer to Table 7-I for approximate guidelines.

For diameters under 4 inches, the SVT032VR model is recommended due to its torque capacity. The SVT042VR model is used where high RPM (>3000) is required.

Please contact the Dukane Applications Laboratory (see Chapter 11) for a recommendation concerning your specific application.
