Formed End Example #1

Micro-Electronics Miniature End Forming

  • Utilized PlasticWeld’s proprietary induction heating system combined with high precision forming dies and actuation system to form two different tight-tolerance 3D shapes on the ends of small diameter tubes.
  • The formed ends mate into receiving slots inside an assistive hearing device, so dimensional conformance and minimal flash were critical attributes.
  • Advantages to utilizing PWS’s technology include: no additional polymers are required – the tubing is formed into the required shape – thus maximizing strength; lower costs versus insert injection molding.

Tip Form

Micro-Tipping for a Drug Delivery Device

  • Utilized PlasticWeld’s proprietary induction heating system in combination with their micro-pneumatic actuator system to form precisely-shaped tips on 2 French sized PEBAX tubing.
  • Proprietary flashless tipping die and mandrel, designed and fabricated in our shop, provided the required tip and through hole quality without sacrificing production speed or adding secondary finishing operations.

Formed Eye Example #1

Smooth Eye Forming for Urinary Catheters

  • Utilized PlasticWeld’s proprietary induction heating system in combination with precision pneumatic actuator systems and custom punches to form precisely-shaped holes in the side walls of various sized PVC tubes.
  • Formed eyes must have smooth edges in transition from the OD of the tube to the side walls of the eyes, and must have minimal flash protruding into the lumen
  • Proprietary tooling design enables fast and repeatable set-ups.
  • Proprietary punch and induction coil designs enable fast production speeds with no loss of formed eye quality.

Tip Skive Tube

Multi-Process Tipping Systems

  • Utilized PlasticWeld’s proprietary induction heating system to form tips on tube ends while simultaneously skiving holes in the side walls of the tube.
  • Custom designed tooling and programming enables combining two operations into a single work station while handling the tubing only once.
  • Precision guide blocks and programmable electric slide assure clean, burr-free cuts along with accurate positioning of the skived holes.
