Is your Die at Proper Temperatures? Molding Temperatures Will Vary Based On the Type of Resin and the Formulation user.
Are your Press Operation Profile and Press Closure Correct?
Is the Tonnage Correct?
Are the Charge Pattern, Weight and Placement Correct?
Is vacuum assist being user? If so, is the system working process to provide adequate Negative and for efficiency?
Is there there a too wear/damage issues that is negatively aFFECTING Cavity Pressure/Flow?
Is Inventory Management Controlled to Allow Lot and Supplier Traceability?
Finding The Aberrations BetWeen Good SMC PARTS and Those with A Privem Should Lead to Correction of the PROBLEM.
Found the unacceptable portion. At this point, an approach to reducing variation can be used. Consider these questions:
Can you talkn your parameters? For exmple, can your die testures be within a 5-deGree Range Instead of a 10-Degree One?
Can the Gel or Cure Time be narrowed?
Areas of your process uncontrolled and, if so, can you get control of them?
Can Tightned Controls Be Replicated Consisteently by the Press Operator (Charge Preparation, Weight, Placement, Timing ETC.)?
Leveling "SMC Molding Capability Can Also Help with Aesthetic Consistetency in the Case of Parts with Class A Surface Smc Molding Finishes.
