6. The blow molding process begins with melting down the plastic and forming it into a parison . The parison is a tube- like piece of plastic with a hole in one end in which compressed air can pass through. The parison is then clamped into a mold and air is pumped into it. The air pressure then pushes the plastic out to match the mold.

Dimensional Stability After Molding—Part 2 | Plastics Technology

The Tg of PP can vary from about -10 C to +15 C (14 to 59 F) depending upon the grade. The Tg of acetals is -78 C (-109 F), or the temperature of dry ice. This is a temperature only rarely experienced anywhere on our planet. So the chances are quite good that wherever you might be using an acetal part, it is above its Tg. Room temperature is 100° C above the Tg of acetal. So as our molded.

Plastic Blow Molding Machines & Molds

PP is easily processed via injection molding (jars and closures), and injection, extrusion, or stretch blow-molding (bottles). One major advantage of polypropylene is its stability at high temperatures, up to 200°F. Therefore, it is used for hot fill products such as pancake syrup. Polypropylene is also autoclavable and offers the potential for steam sterilization. PP has excellent chemical.

10 Tips for Injection Molding Polypropylene Resins

6) Select a mold temperature of roughly 50-150° F. Mold temperatures should be carefully set to reduce stress and surface imperfections. Mold temperatures of 50 -150° F help to prevent these pitfalls. Additionally, make sure that the mold is cooled uniformly in order to facilitate the component’s ejection from the mold.

Cycle Time Calculation for Plastic Parts Injection Molding

The mold opening and closing time is affected by the size of the machine, the mold structure, and other factors. The core pulling structure (row position) on the mold, the mold opening, and closing rack drive mechanism, the three-plate mold (fine nozzle) mechanism, etc. All of them will affect the opening and closing time. Generally, we take below time as the machine`s operating cycle time.

Texturing Molds for Thermoplastics: Factors for Success.

Mold types: Thermoforming and blow molds can be less expensive to texture compared to injection molds. Thermoform molds and blow molds by the nature of their lower pressures don’t replicate the mold pattern as precisely. In other words, what will show up in an injection molded part will not show up in a thermoformed or blow-molded part. The result is you can get away with patterns that are.
