Stockwell Elastomerics, Inc. assists designers and engineers in the technology sector by providing material recommendations, samples and prototypes for the product design and development process. It is commonplace for silicone rubber gaskets and cushioning pads to be the last components specified in a design. Products such as analytical instruments, communication devices and other portable electronic devices that are driving the technology markets must meet strict ruggedizing and sealing specifications. Our product design assistance services include application engineering assistance, material selection and samples, rapid prototyping and fast-turn initial production.
Material Selection and Technical Data.
Our core business centers on the fabrication of high performance elastomers such as silicone rubber, silicone foam, silicone sponge, PORON® cellular urethane, fluoroelastomers and premium grades of neoprene, Buna-N (nitrile) and EPDM.
Our long standing relationships with silicone rubber suppliers permits access to silicone rubber materials and technical developments within leading product lines such as; Cohrlastic Silicone Rubber, Rogers Bisco Silicone Rubber, GE Silicones and Wacker Silicones. This access enables Stockwell Elastomerics to provide technical answers beyond our internal resources. Although our web site contains a variety of materials data sheets, please call us for additional technical information. Being a preferred converter / fabricator; we are in constant communication with our suppliers' technical departments to provide detailed information to assist you.
Material Samples and WaterJet Cut Prototypes.
With the vast array of materials available today, selecting the exact material from data sheets can be a tedious process at best. Our customer service team will help guide you through the material selection process. Choosing one or two materials and requesting samples will allow for testing to ensure that design requirements are met. Stockwell Elastomerics has committed resources to provide sample materials to assist in your selection, samples may be requested with pressure sensitive adhesives to assure compatibility with the mating components of your product.
If an AutoCAD dxf file is provided, we can water jet cut a prototype part within several working days.
If your need is urgent and the gasket is less than 12" x 12", we can normally water jet cut a prototype within 24 hours of receiving your dxf file. Please see the listing of materials we have available to support our Rapid Prototyping Service. Kindly include your UPS Red or Federal Express account number with your e-mailed dxf file and choice of material and thickness.
Rapid Prototyping Material Selection
Fast Turn Initial Production
Die Cutting
The AutoCAD dxf file used to provide prototype water jet cut parts can also be used for initial production if your production schedule is urgent. Our water jet cutting cell operates 18 hours per day, and much of the capacity is dedicated to supplying fast turn initial production in quantities of 10 to 5000 pieces.
If the design in conducive to die cutting, the same dxf file may be used to make a steel rule cutting die. These dies can be made in less than one week. Often a project is converted from water jet cutting to die cutting, as die cutting is a quicker process than water jet cutting and provides a lower production cost.
Liquid Injection Molding (LIM)
Some solid silicone rubber gaskets are more economically produced by liquid silicone rubber injection molding. A single cavity mold for a simple gasket or seal configuration can typically be designed and produced in 2 weeks. As much of our LIM silicone molding capacity is dedicated to fast turn production, we often complete first article inspection and begin initial production of 1000 to 2000 pieces within a week of mold completion.
If your project schedule can not wait for the tooling, we can water jet cut several hundred to thousands of solid silicone gaskets as we await the mold for liquid silicone rubber molding.
