Plastic injection molding is the best way for making plastic caps and closures, especial for complex, high volume caps that require tight tolerances, though cap compression molding is a good method. Check the benefits of the plastic cap injection molding here, and then you can see that it would be the general trend.

Above all, there are two videos to help learning that what plastic cap injection and compression molding are:

Plastic Cap Injection Molding

Plastic Cap Compression Molding

It's really different two ways of molding plastic caps, and for cap compression molding, people would think that it’s an more energy saving and higher productivity way as the its lower temperature and pressure required. And actually, plastic cap injection molding could do better.

Five Benefits of the Plastic Cap Injection Molding

1. High-end Plastic Cap

The injection molding process can be used to manufacture caps in a wide variety of plastic materials in virtually any shape or size, and achieve higher precision and more complex structure than compression.

2. Higher Productivity

It’s not only the instantaneous output, as there are still room for reducing the cycle time of the compression and injection, such as for lighter caps, the cycle time of compression and injection could be both less than 3 seconds. But considering the long-term output, which would include the footprint, maintenance, reliable quality, part changing… there would be better efficiency by plastic cap injection molding.

3. Higher Cost-efficient Investment 

High-output cap injection molding line is pretty important for the popular caps and closures. And it could help you in the lower capital investment as the higher production capacity. So you can see that for the total investment, when the output is much huger, the cost efficiency of plastic cap injection molding is better.

4. Greater Production Flexibility

Plastic cap injection molding process is more flexible, the parameters of cap injection molding could be adjusted quickly to achieve the cap production improvement, such as the cycle time reducing, material changing for different appliance, color changing… By the plastic cap injection molding, it’s freer for the molders to arrange the kinds of caps production to meet the demand of the customer market.

5. Less Energy Consumption

For the energy saving, the output must be considered. That's not only the total energy consumption, but per unit output. By this way, the plastic cap injection molding is more advantaged, as its higher output.
