Our Services

Our Services From Design To Delivery

Most plastic manufacturers offer limited services, such as designing molds, building molds, or molding parts. Typically, they do not provide all three services, often needing to send unfinished products to another company for further assembly and post-molding services. This results in additional costs, customer complications, and production process delays.
At Rilong, We are proud to offer our customers a full list of injection molding services in-house. This safeguards the integrity of your product, while also lowering production costs. If your business is looking for a plastic injection molding or CNC machining supplier contact us and become another happy Rilong customer.
Today, we deliver the high-quality tool and die machining we started with. Utilizing computer numerically controlled (CNC) mills and other advanced machinery, no design is beyond our capabilities. Our factories in Shenzhen and Dongguan also house multiple injection molding machines of varying tonnage to handle diverse injection molding requirements.
We also offer comprehensive sales services, such as updates on your orders, responses to RFQ and any questions, and timely follow-ups for your project situation. In addition to these, we also offer a range of valuable services. These include:
