In injection molding, material is fed through a hopper into a barrel where a reciprocating screw mixes and melts the material then injects it into a mold.
A well-maintained injection molding machine will improve uptime, decrease cycle time and extend the life of the machine. Bottle Blow Mold
Molders have long used the projected area of the parts and runner to guesstimate how much tonnage is required to mold a part without flash, but there’s a more precise methodology.
Here’s how to get the most out of your stationary mold vents.
Here’s what you need to know to improve the quality of your parts and to protect your molds.
There are many things to consider, and paying attention to the details can help avoid machine downtime and higher maintenance costs, and keep the customer happy.
I conclude this three-part examination of real-world problems and solutions involving hot runners by focusing on heaters, thermocouples, and controls. Part 3 of 3.

Plastic injection molding is a cyclical manufacturing process that allows for cost-efficient production of a mass number of identical parts made from either thermoplastic or thermoset materials.
How to Improve Consistency in Injection Molding?
Cushion values in injection molding ultimately are an indication of a part’s quality, especially its dimensions. A consistent cushion will create consistent part dimensions.
How to Get Rid of Bubbles in Injection Molding?
It is important to determine which type of bubble your part has, and what the root cause might be. Determining bubble type will allow you to pinpoint the source and determine your next course of action to eliminate the problem.
How can I improve my injection molding quality and productivity?
Most molders are still relying on “general-purpose” screw designs that go back 30 years. With all of the technical improvements that have been made on machines over that time, nothing has been done to improve melt uniformity. We still use “general-purpose” (GP) screws, which well-known screw designer Bob Dray wisely has called “no-purpose” screws. That is they do not melt plastic uniformly. Processing with a uniformly melted plastic would seem like a high priority, but it has seen little if any attention.
