A container manufacturing system comprising:

• a mold apparatus configured to form an article having a selected configuration and including a body defining a volume, a neck and a dome;
• a trimmer engageable with the article to remove the dome from the article to form a finished container;
• a feed-screw and a conveyor that support the finished container along a selected path;
