Compression Molding: The Pinnacle of Design and Efficiency

Delaware Valley Corp. takes pride in its  history of consulting on  compression molding projects and helping our customers bring them to fruition. The process employs a precise amount of heat and compressive force, pressing the material into a compression mold design and requires just the right fabric to be successful. When the material fits snugly into the mold, which consists of a clamped upper and lower section, it takes the mold’s specific form and produces an excellent finished product.

Notably, compression molding stands out as the go-to choice for synthetic materials, particularly thermosets. Among the various molding techniques, it emerges as the most cost-effective, offering our clients undeniable value.

Benefits of Compression Molding:

• Optimal for low to high volume production, ensuring cost-effectiveness.
• A simplified process leading to reduced production expenses.
• Capability to produce thicker, larger parts.

Thermal Injection Molding

Delaware Valley Corp. also has experience in low pressure thermal injection molding – a complex yet efficient manufacturing technique. This process involves the use of thermal energy to melt specific synthetic materials which are then injected into a metal mold under low pressure. As the material cools, it solidifies, making it one-piece with our needle punched fabric and ready  for subsequent manufacturing stages.

Thermal molding, especially with thermoplastics like polyester and nylon, is superior due to the elevated temperatures the fabrics can withstand.These materials are popular choices in textile manufacturing.

Benefits of Thermal Injection Molding:

• Remarkable efficiency, outpacing many alternative molding techniques.
• Enhanced durability and strength of the final product.
• Vast flexibility in choosing materials and colors.

Sonic and Vibration Welding are Combining Techniques that are perfectly suited for our nonwoven fabrics. 

These methods of combining textile fabric to other materials requires that both the fabric and the material it is being attached to (the substrate) are of thermoplastic polymers and that there is no hindering layer (such as latex backing on the fabric) to interfere with the mating of the two surfaces. Once the compatible materials are placed together in the jig, pins or acoustic heads are brought in contact with enough pressure to push the two materials together under low pressure and the pins or acoustic heads are caused to vibrate at high frequency to create heat through friction in the two materials, thus causing them to flow together at specific points and bond at those points. When the correct needle-punched nonwoven is used with the correct substrate, this can be the most efficient method of combining textile materials.

Our textured and Thermal-bonded nonwoven fabrics with needle punched pile surfaces are excellent for this method of combining rigid and semi-rigid backing materials with visually appealing fabrics and can be used in home furnishings, transportation vehicles, retail store display cases, storage safes, vaults, cabinetry, office partitions, as well as numerous other end uses.

Benefits of Sonic and Vibration Welding

• Extremely rapid and efficient with proper components
• Allows finished textured fabric surfaces to be directly and economically attached to rigid or semi-rigid substrates without attachment points visible
• Entire assembly is thermoplastic and recyclable
