Bonded Manifold Questions

I’m interested in learning a bit about your expertise in bonding of acrylic manifolds.  We sometimes work with complicated fluidic manifolds that need to be optically bonded together.  What kind of processes do you use for bonding of acrylic manifolds? Is this information that you can share? And if not, what would be the approximate cost of having your company perform the bonding for us?

Connecticut Plastics utilizes a proprietary bonding process for Acrylic manifolds. We consider our process the most efficient process available and therefore the lowest cost available to achieve our high level of quality.

 

I am head of a design project for a medical device. I am looking for information on what can be achieved in a bonded manifold.  In our initial concepts we have several parts such as diaphragms, valves and pistons that need to be captured inside of the manifold.  We are not sure if this is possible in all cases.  Also, can you provide me with some direction on how feasible it is to go with bonded manifolds in large quantities?  If we are looking at 10K manifolds a month is that an issue? We originally imagined building these units in our own facility, but not sure that is an option if we need to rely on your bonding techniques.

Each bonded manifold is custom designed specifically, to suit your process requirements. There are many variables that impact feasibility so it is best to work with an experienced bonded manifold manufacturer like Connecticut Plastics during the design phase of your project. Large quantities are not a problem, once your design finalized. A multi-layer bonded manifold may work in your application.

 

I am looking for a manifold manufacturer interested in fabricating the manifold, then adding pumps and valves and finally, testing the overall assembly. I am also interested in getting quotes for manifolds.  The attached files are for a larger manifold.  You will find extrusions that were meant to encompass a fluid path and press it against a gasket. Would your company be interested in quoting this work?

 Assembly work is a specialty. We can support the design and manufacturing of multilayer fluidic manifolds with assembled valves, pumps and fittings.

 

This is a prototype part that our local machine shop is having trouble with.  Fluid circulates through the flow path and electrical measurements are made via the SS contacts.  The plugs must be inserted accurately so that they neither restrict flow in the through path nor leave any dead space in the flow path.  The plugs and SS contacts must be leak tight to water at 20psi.  Delrin or polypropylene are preferred materials.  We can provide Solidworks drawings. Is this a project that you would be interested in quoting?

Manifold manufacturing is a core skill for Connecticut Plastics. Design of the plug is critical. Please consider a bonded manifold solution as an alternative to reduce the plug count. We can bond the SS contacts directly in.

 

I am looking into the feasibility of offering a Polypropylene (FDA approved, USP Class VI) manifold solution instead of the stainless steel manifold that is currently in use.  Our customer would deem these to be “disposable”, so price is an important factor in determining our direction. Currently we have 3 and 5 round designs that I’d like quoted – price and delivery.

Medical grade PP is available however color consistency can be an issue. Also, in thicker Polypropylene sheet, centerline porosity is a concern. Micro bubbles form at the centerline though they are not connected for a leak tight manifold. Leaks at the sealing surfaces at the centerline can be an issue.

 

We are interested in having our fluidic manifold machined. We have attached the files.  We are currently using PMMA as a material but we are interested in using other material perhaps Polycarbonate. We currently need only 5 pieces for prototyping. We are interested in getting a price quote and your recommendation for material.

Our core competency is fluidic manifolds. Polycarbonate can be a better choice for increased chemical resistance.

 

I have left a message with your engineering department regarding this part. I would like to review this design with your engineering team, as it is not currently in a split configuration for fusion bonding.

Ok, we are happy to help with the bonding design.

 

We are interested in developing a water diverter, for allowing a high speed water jet to continue un-diverted with minimal losses.  The switching frequency of the water jet diverter must be at least 10 Hz. We are considering a water diverter configuration that uses the Coanda effect, and one or two air control ports to divert the flow. It is our understanding that with pressurized air, the performance of the diverter can be greatly improved. Normally, for this application, a solenoid valve is used to switch the air at atmospheric pressure to either control port. At this point, we are wondering if it would be more convenient to use a manifold as part of our design.

Multilayer fluidic bonded manifolds are a good choice for this application. We are experts in the process of producing bonded manifolds; please contact our engineering department for help with this project.

 

We are manufacturing micro fluidic chips with integrated interconnects and are interested in bonding our parts. We are now pursuing volume production and would like to know whether you have the capability to bond parts by exposure to solvent. If you are able to handle this application then we would be interested in receiving a quote from your company.

We can bond micro fluidic chips. Our smallest channel size is .004”. Our method reduces the glass transition temperature only at the bond line to avoid feature distortion or translation. Micro fluidic devices are a specialty of Connecticut Plastics.

 

I am interested in producing scaled up cast acrylic micro mixer test sections. I have attached sample pdf files of our designs. Dimensions are in mm. Test sections would consist of 2-3 fused layers. Please contact me if your company would be able to produce these sections.

We specialize in bonding acrylic and can provide a seamless 3 layer assembly.

 

We are designing an assembly of plastic parts made from Ultem and we need to join these parts, creating a hermetic seal between the parts, while maintaining chemical and temperature resistivity.  Can your company help us out in the fabrication and/or assembly of these parts?

We can produce bonded Ultem components in multiple layers with a hermetic seal. Bond strength is typically equivalent to the parent material. Typically the assemblies are used as fluidic devices.
