Delivering perfectly trimmed, milled, and finished plastic bottles at every cycle

In high-volume plastic packaging production, every millimeter counts. Irregular edges, badly trimmed necks, or misaligned handles can disrupt filling, sealing, or labeling. The result: leaks, waste, and downtime.

Delta Engineering’s automated finishing systems for rigid plastic bottles and containers consist of spin trimming, neck milling, punching, and handle or spout application in one continuous flow. In this way, we ensure consistent quality, reduced scrap, and a perfectly finished product. All delivered through a single plug-and-play automated process.

Spin trimming

High-speed rotary trimming removes the lost dome from wide-neck bottles with exceptional precision. Consistent cutting ensures smooth edges and leak-free closures for reliable sealing and a perfect finish.

Neck milling

Accurate milling of plastic necks and threads guarantees precise closure sealing. This step eliminates sealing defects and ensures every bottle or container performs flawlessly in high-speed filling lines.

Punching

Delta Engineering’s automated punching systems allow for drain holes to be added to industrial drums.

Handle/spout applicators

Automated systems attach plastic handles or spouts with perfect alignment and servo-driven control. Designed for flexibility, they adapt to multiple bottle shapes and materials for efficient, repeatable assembly.
