Tips to Bond Silicone Rubber to Aluminum

September 23, 2014

Plasma cleaning of metal parts dramatically increases the success of overmolding.We’ve had a few questions lately about the best method of bonding rubber to aluminum before overmolding. It seems this bonding combination poses a tough challenge. And in many cases, we’re finding that companies want to achieve better bond strength without using harsh solvents. So how can you achieve one without the use of the other? Plasma cleaning is the answer.

Prototype to production - Custom solutions for you application

November 8, 2011

I’ve noticed an uptick in requests for our custom fabrication services.  In fact, we are currently collaborating on new ingress and egress components with a big city transit system.  I’ve found that many of our clients are not aware of the range of our custom abilities, nor do they realize that we design and build everything in-house to help save on product lead time and delivery.  Our facility has complete CNC milling, turning, and Swiss screw machining capabilities to give you the exact fit you need.  And we also do custom bonding – to help your part better accept paint, for example.

Enhancing the Bond Strength of Cement Through Plasma

March 2, 2010

We've all been touched by the recent earthquake destruction in Haiti. And our team is now seeing a renewed interest in surface treatments that can help building materials (like cement) resist seismic activity and sudden impact.

Polymer Refresher: Part 3

December 14, 2009

The molecular forces and chemical bonding are important to understand the physical properties the bulk polymer exhibits. The covalent bonding in a polymer system is one of the strongest and significant forces and is often referred as primary bonding. A list of common covalent bonds and the energy associated with the bonds are listed below:

A copolymer, though, is a polymer that has different numbers of repeating units. Copolymers are grouped according to the arrangement of the units in the polymer backbone.

Polymer Refresher: Part 1

December 2, 2009

A polymer is a very large molecule (macromolecule) composed of many small repeating molecular units (monomer). Polymers are formed from atoms that are capable of multiple covalent bonds. Such as the carbon atoms in ethylene CH2=CH2 molecule. Molecules with this type of bonding are said to be unsaturated. These compounds tend to keep this structure yet will readily react (under heat and pressure) to form more stable single bond structures; they will form a saturated compound. For example, ethylene will react to form polyethylene [-CH2-CH2-']n . The [n] signifies the number of repeating units in the polymer backbone. This number can be from 1000 to ~300,000 units. The polyethylene material will have different properties based on the number of repeating ethylene monomer units.
