Acrylic Bonded Manifold Multi Layer Manifold

Ultem Multilayer Bonded Manifold

The laboratory and diagnostic instrumentation market constantly demands smaller, more compact equipment. Bonded multilayer fluidic manifolds can be a good choice to achieve the packaging size reduction. A multilayer manifold is frequently a single manifold replacing the traditional tubing connections between multiple manifolds. The layers allow vertical integration and encapsulation of the connections between various components such as pumps and valves. Bonded fluidic manifolds have many advantages over the traditional tubing layout such as:

Smallest possible size for a given circuit with an associated weight reduction
Reduction in tubing and connection points lowering the likelihood of leaks
Clarity to better visualize and understand the fluid flow
Simplified assembly on the manufacturing floor
Single part cleaning requirement
Simplified field servicing
Reduces product complexity
Component mounting directly on the manifold
Zero entrapment area, no unswept volume

Connecticut Plastics' proprietary bonding process is unique and superior to other manufacturing techniques for multilayered bonded manifolds. Manifolds can be manufactured in Acrylic, Polycarbonate, Polysulfone, PVC and Ultem

Need help with the design of a fluidic multilayer manifold? As part of our service in manufacturing bonded manifolds, our engineers are happy to help design the manifold. From the schematic through production, we can provide a complete solution to your manifold needs.

NEW! Rapid response capability : Connecticut Plastics has now added quick turn capability for bonded manifolds. Less complicated prototype designs can be built in as short as 1 - 2 weeks.

Bonding method comparison	CT Plastics	Competitors
Bond Strength	Equal to parent material	Less than parent material, delamination possible
Injection Molded Blanks	Yes	No
Channel Shape	Any configuration possible, full circle to single side	Prefers D shaped single side, full circle more expensive
Channel Size	Can hold tight tolerances in full circle channels. Microfluidic channel size to .012"	Channel distortion. Does not retain original shape. Typically no smaller than .020"
Channel Position	No feature translation, channels stay straight	Long straight channels frequently curve and bend. Features move during bonding.
Large cavities	Any cavity size possible	Large cavities collapse
Feature placement	Threads including pipe taps machined on the bond line	Bond line threads discouraged, no pipe taps
Tooling	Minimal specialized tooling required	Large tooling cost
Design Limitations	Few	Constrained
*Delivery*	2 weeks for prototypes, 4 weeks for production	12 weeks typical
*Cost*	Lowest cost in the industry for similar quality	Expensive
