Made in the USA Butterfly Valve

Posted by Becky McMorrow, Marketing Manager at Davies Molding

butterfly-valve-thermoset-moldedWe have a long history of manufacturing plastic knobs, especially phenolic plastic knobs.  But we also mold phenolic custom plastic parts, such as the plastic butterfly valve for the oil & gas industry. We started manufacturing butterfly valves a few years ago because the company that needed them got fed up with their overseas vendor. 

Long lead times, poor communication, and inconsistent quality from their overseas vendor made them decide to source domestically, and Davies Molding got the call to quote. We were able to manufacture a butterfly valve that met their strict quality standards and short lead times.  We chose a compression molding process using a phenolic material that is chemical and water resistant – key attributes for a butterfly valve.  We now manufacture a large range of sizes of butterfly valves along with other custom compression molding.

It's in the details -specialized packaging for plastic knobs and handles

Posted by Becky McMorrow, Marketing Manager at Davies Molding

Quality needs to continue even after your plastic knob or handle has been made.  Improperly packaged parts can cause defective goods, resulting in lost manufacturing time and lost revenue. Davies Molding provides a variety of packaging requirements such as bagging, layer packaging, clamshell or blister packaging, and bar code labelling to make sure your plastic knobs and handles arrive securely packed the way you need it.  Here is a list of some specialized packaging for plastic knobs and handles:

  • Bagging: Thermoset Phenolic Knobs are durable and heat-resistant, but can be prone to chipping if not packaged plastic_knob_bagging_imageproperly.  Wrapping and bagging are important for phenolic knobs to ensure they arrive for your project in proper shape. At Davies Molding, we make sure our phenolic knobs are packed properly to arrive in pristine condition


  • Egg Crate Packaging: Just as the name implies, we pack some of our knobsplastic-knob-egg-crate-pkg that require extra care in egg crate style packaging.  This is important for knobs shipped long distances and with intricate designs



  • Layer Packaging: Layer packing is a cost-effective way to pack knobs and handles for long distance shipping and keeps the parts in an easy-to store package for longer-term storage. Thin cardboard inserts separate each layer and protect the knobs from chipping


  • Barcode Labeling: In addition to offering packaging that protects your plastic knobs and handles, Davies Molding provides bar code labeling to track and  identify the parts at your manufacturing facility.





Need help deciding which packaging might work best for your plastic part?  Call us today at 1-800-554-9208 for more information.

Davies Molding Company...Plastic Knobs Then & Now

Posted by Becky McMorrow, Marketing Manager at Davies Molding

Oct 21, 2013 10:15:42 AM

Harry_Davies_Molding_CompanyIn 1933, the Harry Davies Molding Company began with only seven molding presses and three punch presses, located in downtown Chicago. This 1960's picture, in front of the molding facility at 1428 N. Wells St., lists the phenolic material molded at that time: Bakelite, Beetle, Durez, Durite, Makalot, Plaskon, and Resinox. The Harry Davies Company also molded the popular Daka-ware brand of ashtrays and cookware knobs and handles.

80-year-anniversary-co-pictDavies Molding is now located in the western suburbs of Chicago, and its 99,000 square foot factory houses 72 presses, including thermoplastic injection molding, thermoset compression molding, transfer, and two-shot injection molding. We celebrated our 80 year anniversary as the largest manufacturer of insert-molded plastic knobs and handles this year, and recently took a picture outside the Carol Stream, IL location.  Davies Molding still molds thermoset phenolic and thermoplastic knobs and handles, as well as custom components for the automotive, medical, oil & gas, and other industries.  Want to learn more about Davies Molding's plans for the next 80 years?  Check out the interview with Davies' president Derran Smith here.

The answer is clear- plastic knobs with clear skirts

Posted by Becky McMorrow, Marketing Manager at Davies Molding

Oct 18, 2013 3:09:00 PM

Clear-skirt-knobs_3Plastic knobs with clear skirts are used primarily in the food service equipment and electrical industries.  The clear skirt accentuates the printed graphics and gives it a “pop” unlike conventional aluminum skirts.  Another benefit of using a clear skirt is the ability to print on the back side of the skirt, which even after many years won’t rub off like traditional pad printing on the top side of the skirt.  Want to learn more about clear skirts? View the clear skirt part specification and search for additional skirted control knob information.

Reduce Costs by switching your metal parts to plastic

Posted by Becky McMorrow, Marketing Manager at Davies Molding

Sep 30, 2013 7:47:12 AM

metal-to-plastic-water-tankAre your metal parts rusting or denting?  Do you need multiple operations such as welding and bending to machine your metal part?  If you answered yes to either of those questions, you should consider switching to a plastic part.  Plastic parts resist rust and denting, can be custom colored, and have high impact strength - not to mention are cheaper to produce.  Want to learn more?  We've put together a 24-page ebook to help you learn more converting metal to plastic parts and about the molding process-click here to download the guide, or call to schedule a design consultation today.  Visit our product portfolio to learn more about metal to plastic conversion parts for the Automotive, HVAC, and food Service Industries.

Plastic Knobs and Handles - The Insert Molding Advantage

Posted by Becky McMorrow, Marketing Manager at Davies Molding

Sep 23, 2013 11:48:04 AM

insert-molded_clamping_knobInsert Molding is a plastic-metal parts production process that combines metal components, such as contacts, cast metal, metal stampings, nuts, screw machine parts, screws, shafts, etc., with a thermoplastic or thermoset material (or multiple materials) into one single unit. 

Some typical examples of products manufactured utilizing insert molding would be screwdrivers (handles around screwdriver shafts), plugs (prongs within a plug housing), and electronic connectors (contact pins within a connector housing). It is frequently the preferred method for producing electrical and electronic assemblies, but there are a plethora of other applications.


 insert-molded_plastic_ball_knobsThere are major benefits associated with the insert molding process.

  • Product design flexibility.
  • Lighter weight compared to traditional manufactured assemblies.
  • The reduced assembly/labor aspect of insert molding frequently offers significant cost savings to the client.
  • When an aggregate of parts are secured firmly together  in thermoplastic material, product strength, integrity and reliability are usually enhanced.

insert-molded_t_bar_clamping_knobSome insert molding design considerations would be materials, required insert pull strength, leak resistance parameter,  potential maximum torque (that may be applied to the insert) and in an electrical application, maximum voltage.
