Radio Frequency (RF) Welding, RF Sealing & RF Tooling

Kabar Manufacturing Corporation


We have agents and service personnel located in New York, California, Florida, Missouri, Georgia, Illinois, Texas, Ontario and Quebec. Please call our main office so we can direct your call to the appropriate representative.

Cosmos Electronic Machine Corporation, along with its wholly owned subsidiary, Kabar Manufacturing Corporation is the largest U.S. manufacturer of RF heat sealing equipment. D&L Die Corporation, is the largest RF die shop in the U.S. that manufactures RF heat sealing tools and RF heat sealing fixtures.

RF (Radio Frequency) Equipment

RF stands for Radio Frequency, which is energy that is created by the RF equipment to weld specific types of thermoplastics. RF excites the molecular structure of the material causing it to heat very rapidly. Once heated, an RF die forced into the material by a press, determines the final shape and characteristics of the finished sealed product. RF welding is also known as RF sealing, radio frequency welding, dielectric bonding, dielectric interface, dielectric sealing, dielectric welding, dielectric heat sealing, dielectric interface, electronic heat sealing, high frequency welding, high frequency sealing, HF sealing, HF welding, induction heating, bar sealing, blister sealing, blister welding, clam shell sealing, custom RF welding, custom RF sealing, electronic heat sealing, industrial sealing, industrial welding, low dielectric welding, medical radio frequency sealing, package heat sealing, package sealing, plastic sealing technology, PVC welding, and RF bonding.

RF Tooling Manufacturing

In addition to our RF equipment, we offer our customers full service RF tooling manufacturing, capability for true "Turnkey" solutions for their entire RF sealing production. RF tooling, which can be referred to as heat sealing tools, heat sealing tooling, package tooling and dies, sealing dies and tooling, or welding tooling is an essential part of the RF sealing process. Without a quality custom RF die manufactured for an RF welder, your product may not be sealed efficiently.
