Thermoset plastic molding is an advanced manufacturing process that enables the creation of highly customized parts with enhanced design flexibility, superior strength, exceptional durability, and excellent chemical resistance. Unlike thermoplastics, thermoset products maintain their structural integrity over time, making them ideal for demanding environments where quality is crucial. Additionally, the minimal shrinkage exhibited by thermoset products during the curing process allows for intricate details and precise customization options, further expanding their versatility. Thermoset plastic parts are produced by utilizing heat and pressure to transform raw materials into precisely shaped parts. In contrast to thermoplastic molding, thermoset molding involves the application of high pressure to room temperature pellets or powders, which are then introduced into a heated mold. Within the mold, the polymers in the material undergo cross-linking during the curing process, resulting in an unbreakable and irreversible bond. The pellets or powders used in this type of molding commonly consist of epoxy, phenolic, or polyester resin. While thermoplastic molding has traditionally enjoyed greater popularity, manufacturers are increasingly embracing thermoset molding due to its array of advantageous features.

What are the key benefits of thermoset molding?

1. 1. Design Flexibility: Thermoset molding allows for a wide range of design options. Including the ability to produce complex shapes along with details not available in traditional molding. This makes thermoset products an ideal choice for custom molding project.
   2. High strength: Thermoset plastics are known for their high strength and stiffness. This makes them ideal for producing thinner parts, parts with longer ribs, and other features that require high strength-to-weight ratio. Parts produced using thermoset molding can withstand high stress, making them suitable for applications where durability and reliability are required.
   3. High and low temperature resistance: Thermoset plastics are capable of withstanding high and low temperatures without melting, becoming malformed or broken. This means that parts produced using thermoset molding can be used in high-temperature or very low temperatures applications, where other plastic materials would not hold up 
   4. Low shrinkage: Thermoset plastics are ideal for applications where tight tolerances, precise measurements and details are critical. During the curing process, thermoset plastics experience minimal shrinkage allowing for more complex dimensions and details which are difficult to achieve with other molding processes. Plus, thermoset parts will retain their shape and size over time and in harsh environments.
   5. Chemical Resistance: The resins used in making thermoset parts are resistant to acids, alkalis, solvents, and oils making these parts ideal for more demanding environments.

What are some use cases for Thermoset?

Thermoset molding is a rapidly expanding option across many industries as companies look for parts that can hold up under extreme conditions. Below are some of the industries where you will find thermoset molded parts:

1. 1. Electrical: Thermoset parts are used for insulators, circuit breakers, transformers, and other electrical components where there may be high temperature or stress.
   2. Industrial equipment: Thermoset parts are used in pumps, valves, and compressors.
   3. Energy and power generation: Thermoset parts are used in wind turbine blades, solar panels, and power plants.
   4. Consumer goods: Thermoset parts are used in electronics, appliances, and sporting equipment.
   5. Construction: Thermoset parts are used in pipes, fittings, and roofing materials.
   6. Marine: Thermoset molded parts are used in boat hulls, decks, and interiors.
   7. Automotive: Thermoset molded parts are used extensively in the automotive industry for engines, electrical systems, and different components on the inside of the vehicle.
   8. Aerospace: In the aerospace industry, thermoset parts are used for aircraft interiors, engines, along with structural components.
   9. Medical devices: Thermoset parts are used in many different types of medical devices, including surgical instruments, diagnostic equipment, or implants.
   10. Military equipment: Thermoset parts are used in weapons, vehicles, and aircraft.

Thermoset molding companies offer this advanced manufacturing process that produces parts with a range of benefits over traditional plastic molding including better details, greater strength, higher durability, and superior chemical resistance. Thermoset molded parts are the perfect solution for companies seeking high quality customizable parts that will outlast standard plastic parts.

Thermoset and thermoplastic material is often used for making various plastic parts, including knobs, handles, controls, containers and more. While these two types of plastic materials are alike, they are different in their chemical properties and therefore used in different applications, Each type has unique advantages and disadvantages in how they can be used and we will review each below.

We are pleased to welcome Yusuf Waxali to Davies Molding. He has recently started the position of Mechanical Engineer. After graduating from the University of Illinois at Chicago in 2016, he worked at the Intec Group, a tier-two automotive plastic injection molding company. There he developed strong skills in CMM programing and injection molding simulation. 

It's summer time!  That means time for BBQs, pool days and college interns at Davies Molding.  We're excited to have a marketing intern this summer, Claudia.  Claudia will be working on various marketing projects including: updating product information, assisting with website projects, working on social media and much more.

How does 3-D printing technology affect an 80 year old plastic knob and custom plastic parts manufacturer?  That was one of the questions that was asked to Derran Smith, President of Davies Molding, in a recent interview on CEO Intronet.

Shifter knobs can be found in vehicles, cranes, tractors, and other types of machinery where manipulating gears are required. Davies’ shifter knobs can be customized to meet specific requirements such as operating instructions or customer logos. Secondary operations include laser engraving, pad printing, or hot stamping, applying inlays or mylars, color matching, drilling, machining, and a new finishing trend- hydrographic printing.

Hydrographic printing is a popular trend for adding customizable designs, colors, and textures to shift knobs.  As you might have guessed, it's a water-based printing process and a  high gloss polyurethane hydrographics clearcoat makes the printing durable and long-lasting.

Nothing is more important than choosing the right material for your plastic knob or handle.  Careful consideration of the end user and application can save time and money in the long-run.  Don’t know where to start?  Here is list of materials for both thermoset molding and thermoplastic molding and their applications to get you started.  Talk to our highly trained technical sales and engineering staff if you have questions.  We work with hundreds of various materials and constantly reviewing new materials as they come on the market. 

What materials are available for plastic knobs and which is right for my application?

Luckily Davies Molding is close to Chicago, so I get to take a few hours out of my work day to go down to manufacturing shows at McCormick Place and check out some cool new stuff in manufacturing.  On Thursday I visited FABTECH to see what's new in the welding and fabrication world.  Here are my 3 takeaways from the event:

Quality needs to continue even after your plastic knob or plastic 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 labeling 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:
