The Journal.
Notes from the molding floor for the engineers who spec our resins — tolerances, failure analysis, material data, and the occasional teardown. Written for people who read cut sheets for pleasure.
All entries.
Preparing for Takeover Tooling
Pellet 2 Part, Vol 10: With the right preparation, moldmakers can insulate themselves from takeover tooling crises and add greater value to the molder.
Designing a Better Heat Exchanger: Part 3
Pellet 2 Part, Vol 9: Designing a Better Heat Exchanger: Part 3
Controlling Your Hot Runner Manifold System
Pellet 2 Part, Vol 7: Moldmakers and molders need to better understand modern hot runner controller technology to solve processing problems.
Considerations for Assessing Robotics Requirements
Pellet 2 Part, Vol 6: Knowledge of part de-molding, end-of-arm tooling construction, part defects caused by the mold-robot interface and available automation options is key for suppliers looking to add greater value.
Designing a Better Heat Exchanger: Part 2
Pellet 2 Part, Vol 5-2: In part two of our three-part sub-series on mold water cooling systems, we review water quality and its impact on mold performance.
Designing a Better Heat Exchanger: Part 1
Pellet 2 Part, Vol 5-1: Considerations for mold water cooling systems
Controlling the Melt Delivery System Heat Source
Pellet 2 Part, Vol 4: Understanding the heating systems along the melt delivery path is critical to setting up a robust process and properly diagnosing problems.
The Pellet Enters the Melt Delivery System
Pellet 2 Part, Vol 3: Choosing a hot or cold runner system is a decision for the molder and moldmaker that must balance the processing window with budget and time.
Initial Pellet Contact is the Screw
Pellet 2 Part Vol 2: The machine’s reciprocating screw is often misunderstood and applied to the process incorrectly.
Plastic Injection Molding Starts with the Pellet
Pellet 2 Part Vol 1: What every moldmaker should know about raw materials, including the fundamentals of viscosity curves, Melt Flow Index, Melt Flow Rate, shear and more.
