Diamond Mold (Shenzhen Diamond Mold Co., Ltd.) is a Shenzhen-based manufacturer of injection molds and plastic parts. Its website positions the company as a Custom Injection Mold & Molding Manufacturer. Its services cover mold design, mold manufacturing, mold trials, injection molding, and downstream assembly, serving industries such as home appliances, industrial controls, consumer goods, automotive parts, beauty devices, and medical devices.
The website highlights one-stop engineering services. In the early stage, it offers free DFM manufacturability analysis to identify issues such as wall thickness, draft angles, gates, shrinkage, undercuts, ejection, and material suitability. In the middle stage, it provides mold design, mold flow analysis, hot-runner/cold-runner systems, multi-cavity molds, two-shot molds, gas-assisted molds, threaded/core-pulling/insert molds, and related design and manufacturing. In the later stage, it can handle mold trials, debugging, injection-molding production, and product assembly. Supported injection-molding materials include ABS, PP, PE, PS, PC, PA, POM, and TPU. The company claims part weights of 1g-5kg, tolerances of ±0.01-0.05mm, and production volumes ranging from low-volume runs to million-unit scale.
The official website does not provide a standard price list; this is a typical B2B project-based quotation model. DFM analysis is described as free, while mold design fees depend on part complexity, mold structure, and lead time. The mold manufacturing FAQ states that there is usually no minimum order quantity. Payment terms are 30% deposit and 70% balance, with T/T and L/C supported.
The main advantages are a complete service chain and detailed engineering process descriptions, making it suitable for hardware projects that need to go from drawings to mass production. It also covers a relatively wide range of complex mold types, and early-stage DFM can help reduce the risk of rework after tooling begins. The drawbacks are that the website lacks verifiable equipment models, capacity data, certificate numbers, and real case studies. The English pages also contain spelling errors and placeholder text, so the professional presentation could be improved. Its claimed ISO quality control is only stated in text; buyers should request certificates, samples, and inspection reports.
Diamond Mold is suitable for brands, hardware startups, industrial product companies, and foreign-trade buyers that already have structural drawings for plastic parts and need tooling plus injection-molding mass production through the Chinese supply chain. It is less suitable for platform-style purchasing where buyers want instant online ordering, transparent standard pricing, or very short-lead-time prototypes.
This is the official website of a Shenzhen-based Chinese company and is generally directly accessible from China. If you plan to work with them, it is advisable to manage risk through an NDA, drawing review, sample prototyping, factory audit, and staged payments.
