Selecting the right resin is only half of the equation; choosing the right supplier can make or break your production schedule and product quality. Many manufacturers focus on the price per pound, but selecting a poor supplier can lead to delays, inconsistent quality, or missed specifications.
At Marval Industries, we've been supplying thermoplastic materials for decades, and we know what differentiates a reliable supplier from the rest. We understand that working with an experienced, service-oriented supplier is crucial.
Looking beyond price
Price per pound is essential, but it shouldn't be the only factor. Consider these criteria when evaluating suppliers.
- Diverse product line and customization options: Your supplier should offer a wide selection of resins and additives to meet different application requirements. A company with in-house compounding capabilities can tailor materials to your specifications, rather than forcing you to compromise with off-the-shelf products.
- Quality assurance and standards: Ask about the supplier's quality control processes, certifications, and traceability systems. Established suppliers adhere to recognized standards such as ISO or ANSI and maintain rigorous testing protocols. Material certificates and lot-specific data help ensure consistency and accuracy.
- Industry experience and technical support: Experience matters. Suppliers with in-depth knowledge of resin properties and processing can offer valuable guidance on material selection, troubleshooting, and regulatory compliance. Look for access to technical specialists who can help you optimise your formulations and processing parameters.
- Reliable logistics and location: Delivery reliability is critical. Inquire about inventory levels, lead times, and shipping capabilities. Suppliers located closer to your manufacturing site can reduce freight costs and improve responsiveness. Ask whether the company offers just-in-time delivery or stocking programs to minimize downtime.
- Reputation and customer service: Verify references, customer testimonials, and the industry's reputation to ensure quality. A good supplier should have a track record of responsive communication, on-time delivery, and a willingness to resolve issues. Site visits can offer valuable insights into a company's manufacturing capabilities and cleanliness standards.
- Sample evaluation: Before committing large orders, request samples for testing to ensure quality. A supplier confident in its product will be willing to provide trial quantities and assist with testing protocols. Evaluate samples for appearance, performance, and processability.
