Microfluidic Manifolds Innovate Cancer Research

Microfluidic manifolds are precision machined from high tech polymers and used in blood or fluid assays in medical labs. Manifolds are becoming more popular in medical and diagnostic devices as their use minimizes tubing, simplifies assembly, and provides better visuals.  Overall they reduce product complexity and overall costs.  We are getting more and more calls for them from our customers. Microfluidic manifolds and bonded manifolds are considered one of Connecticut Plastics’s core competencies.  Today microfluidic manifolds are being used in cancer research in medical labs and universities across the country. The following link will take you to an article that […]

Manufacturing Will Come Back to America

In America, we make things. It is what we do best. Our economy hums along when we are designing, building and creating. During the 19th Century our economy switched from agrarian to manufacturing. People left the rural areas and moved to the cities for jobs and the middle class was created. Manufacturing has in the past, provided good paying jobs for skilled workers. It can and will have that role again, in our American economy. Here’s why: In what now seems like an idea gone wrong, many jobs were sent overseas to save on labor costs. In the 1990’s American […]

A Medical Device Saved My Life Facebook Page

This is an interesting Facebook page. It is called A Medical Device Saved My Life. Anyone can post on this page; that is, after you “like” it. Then you can put up a story about yourself or a loved one, and how a medical device was instrumental in saving a life. Currently there are stories by people whose lives were saved by devices such as the artificial lung, a ventricular assist device, and a story about the inventor of the IsoFLow Infusion Catheter, which clinical trials show will cut off blood flow to a cancer tumor while also feeding chemotherapy drugs directly […]

How Plastic Parts Improve Our Daily Lives

Plastic parts are known for their strength, insignificant weight, and malleability. They are used in countless items in our daily lives to add security, confidence, and safety. Most people wouldn’t know it but there can be plastic products in our blankets and even our pillows to help maintain comfort as we sleep! While on the go, the plastic components in water bottles and ice chests let us tote our food & drink nearly anywhere. The precision plastics found in electronics (such as our cell phones and laptops) let us access the Internet or call friends and family while on the […]

Connecticut Plastic Fabricators Reduces Your Lead Time

There is intense pressure to remain competitive, flexible and cost-effective in the plastic fabricators market. OEM manufacturers constantly strive to increase market share while streamlining production and cutting costs. The medical device market is a perfect example. According to Moody’s, alliances between hospitals and doctors have reduced the influence medical device manufacturing makers have in selling products directly to physicians. In the future it is hospitals that will be making the purchases. Hospitals operate under budgets and therefore have many reasons to demand price cuts. The plastic fabrication machine shop that can reduce lead times and produce quality parts will […]

Polymer Tensile Strength in Manifold Design

As plastic becomes more and more the material of choice for machined plastic manifold blocks, polymer tensile strength becomes a very important mechanical property design criteria. Plumbing and component connections, typically utilize a threaded attachment mechanism. This attachment can result in high tensile stress on the plastic manifold block and result in the failure of what could be very expensive precision plastic components. We have seen these results when the wrong material is used in the manifold design. Acrylic offers a cost effective plastic with high clarity after machining and polishing. This makes it desirable for manifold applications. However, if […]

Plastic Selection – A Guide for Machining Components

Machining components can be advantageous for applications requiring low volume production, close tolerance dimensions and/or difficult to mold configurations. There is an array of plastics to choose from; highly engineered, high performance products to low cost, low performance. Determining the appropriate plastic for a particular application can be challenging which is why we’ve put together this plastic selection guide. Typically an engineer will require 3 or less characteristics that are critical to the functionality of the component. A basic search will prioritize and look for a material that can supply all three. The below list presents the most common selection […]

Plastic Component Design Tips

The following are guidelines for good machined plastic component design. These are not hard rules but suggestions to maintain reasonable pricing. Exceeding the guidelines will usually result in higher effort and cost for the fabricated component. Each part configuration and application is unique. For specific component design support view our custom plastic parts or contact Connecticut Plastics’ engineering at 203-265-3299. Flatness: From the extrusion and cooling, plastics have stress gradients through their cross section which are not relieved by post processing at the manufacturer. Plastic’s flatness stability is substantially lower than metals. Consider the following to improve. Balanced design. Dish […]

Plastic Stress Test Protocols

High stress levels in plastic are a common cause of component field failures. Stress cracks or surface crazing near stress concentrators like threads can be a sign of future problems. Sometimes stress is not visible until the component is subject to loading or exposure to chemicals by the end user. PEP Connecticut Plastics has protocols for testing components for stress after machining. These range from total destructive testing to optical stress measurement. While not all components require annealing, there may be advantages for some materials and part configurations. Materials most sensitive to field failures are Acrylic, Polycarbonate, Ultem, Polysulfone and […]
