1. Production capacity and scale: Production capacity and scale directly determine the production tasks and order volume that a factory can undertake, and are also important criteria for determining whether an enterprise has qualifications and strength. Choosing manufacturers with larger scale, advanced equipment, and exquisite technology is more guaranteed.

2. Quality management system: Quality control is very important in the manufacturing of plastic injection molds. A factory with a strict quality management system can provide customers with more stable, safe, and high-quality products, while also improving production efficiency and reducing risks such as product recalls.

3. Process standardization: Standardized processes can help save time and costs, shorten delivery times, improve production efficiency, and enable customers to receive faster and better quality services. This is also an important factor that customers should consider when choosing a manufacturer.

4. Technical level: Technology is the core competitiveness of an enterprise, and a professional technical team can provide customers with more high-quality and effective solutions, while also ensuring product production accuracy, process stability, and cost control. Choosing a manufacturer with a professional technical team and continuously introducing advanced equipment and processes will be more beneficial to customers.

5. Service awareness: Good service not only includes various links such as pre-sales, during sales, and after-sales, but also requires a focus on communication and cooperation with customers from the beginning of production, adhering to the concept of "customer centeredness", and allowing customers to have a satisfactory experience throughout the entire transaction process.
