7. How can I resolve disputes with my supplier regarding product quality or delivery?
   Establish clear communication channels and documentation from the outset to manage expectations. If a dispute arises, refer to the terms outlined in your contract, including penalties for delays or quality issues. Engage in open discussions with the supplier to address concerns, and consider mediation or arbitration if direct negotiations fail. Keeping a record of all correspondence and agreements can help substantiate your claims and facilitate resolution. Building a solid relationship with your supplier can also aid in resolving disputes amicably.

8. What are the environmental implications of choosing between compression and injection molding?
   Both molding processes have environmental impacts, but they differ in material waste and energy consumption. Injection molding is generally more efficient, producing less waste due to its precise material injection. However, the initial energy required to create molds can be higher. Compression molding, while often more wasteful in terms of material, can be advantageous for larger parts where material efficiency is less of a concern. Consider discussing sustainability practices with suppliers, such as using recycled materials or energy-efficient technologies, to align with your company’s environmental goals.
