"Our company has been using the AB Machinery plastic injectors since we grabbed the very first model right off of the table at a trade show in the late 1990s.


We now have a good number of AB-400 machines, and they have served us very well over the years. They allow a wide range of repeatable control settings, are designed and built very well, and have proven to be highly reliable with a wide range of materials.


Also, they are well supported by knowledgeable staff who have always answered the phone personally, and gotten the job done for us.


We have been very happy with the performance of both the machines and the people at AB Machinery."
