Injection Molding Cooling Techniques and Issues

• Pressure Relievers Behind Bumper: These could be causing leaks if the seals are worn away.
• Dry Rot in Seals: Dry Rot in Seals around doors/windows can lead to leaks.
• Cabin Air Vent Drain: Clogged drain can lead to leaks, check the cabin filter and drain pan.
• Sunroof: Leaks can sometimes originate from Sunroofs.
• Mold Inspection and Cleaning: Use hose to identify leaking section and address issues accordingly.
• Silica Gel Packs: Helpful for absorbing moisture to prevent mold.
• Spiders in AC Vents: A potential cause of leaks.
• Design Flaws in Vehicle Doors: Can result in leaks in the passenger compartment.
• Rubber Boot for Wiring Harness: Check for any displacement that could cause leaks.
• Mildew Control: Humidity can lead to mold and mildew if a vehicle is left parked for a period of time.
• Vapor Barrier Tears: Tears can contribute to water entering the vehicle.
• Hose Testing: Run water over sections of the car to identify leak sources.

Injection Molding Cooling Techniques

• Controlled Mold Temperature: Mold temperature control is essential for successful injection molding.
• Cooling Channels in Molds: Used to cool the plastic, can either heat or cool the mold.
• Optimal Mold Temperatures: Vary based on material and design requirements.
• Cooling Line Design: Determines how efficiently the mold is cooled.
• Material Drying: Ensure the material is dry to prevent splay issues.
• Shearing and Injection Speed: Adjust injection speed to reduce shear rate.
• Venting and Flow Analysis: Venting can help minimize splay and improve the molding process.
• Material Moisture Content: Check for signs of wet material before injection.
• Thermocouple Checking: Ensure accurate temperature readings to prevent issues.
• Back Pressure Adjustment: Increasing back pressure can address splay problems.
