how much double shot molding

Calculate Shot Size Vs. Barrel Capacity | Plastics Technology

For PS the melt density is 0.945 g/cm 3 and for PP it is about 0.74 g/cm 3. This changes the ratio for our calculation; it is now 0.945/0.74 or 1.28. Now we need a minimum of 6.16 x 1.28 or 7.88 oz of shot capacity. We are still (just barely) within our 8-oz barrel capacity, but unfortunately Mr. Murphy is still lurking.

Shot Size. Now calculate the shot size by multiplying the part’s volume times the number of cavities, and add the runner’s volume—all in cubic inches. That’s the total shot volume in cubic inches of polystyrene, which is the same unit of measurement in which a molding machine’s injection capacity is rated.

What is Overmolding? - Injection Mold, Plastic Molding Company

Over molding are categorized into 3 types: insert molding, double shot molding, co-injection molding. Insert molding: The most commonly used to mold soft elastomers to rigid plastics, insert molding is the most economical way to do overmolding.

Injection Molding: Fill Based on Volume, Not Weight ...

Somewhere between 90 to 99.9% full—based on volume, not weight. Factors that influence this are the type of part, number of cavities, balance of filling, a weld line at the end of fill, a living hinge, etc. Bottom line for 99% of parts being molded: The first-stage part (s) should be visibly short, not full with sink.

A Simpler Way to Calculate Shot Size vs. Barrel Capacity ...

The barrel is basically a big syringe. Again, with a 164 g shot of PP, the calculations would be: 164 g/0.70 g/cm3 or 234 cm3 volume for PP. Add 10 % for safety = 257 cm3. Barrel size needed: 0.65 x = 257 cm3, x = 395 cm3. If you work with volumes for the screws available, you are done.
