Rapid Prototyping & Low Volume Manufacturing
We provide high quality prototypes & low volume manufacturing service for a wide range of product categories, bridging the gaps between digital files & real products through Vacuum Casting, CNC Machining, 3D Printing & Injection Molding!
Who we are?
Rapid prototying is the nice pair of new product development, and it is the starting point for all of our business. At Shenzhen Tengrui Fumo Technology Co., Ltd, we are specialized in on demand manufacturing of physical models, analyzing & casting products upon the specific requirement. From 3D reviewing to finish the prototypes, we are not only checking all factors of prototype casting, like materials, dimensional tolerance and functional purpose, but also keep it in mind the optimization of mass production in future. Since our inception in 2012, the full fledged engineering team of Tengrui, liaised with tens of engineers, design companies & SME, in sampling car accessories, health & medical appliances, household appliances, baby cradles, industry tools & much more for prototype casting , in addition to low volume manufacturing & mass production. Nowadays, Tengrui factory consists of more than 80 team members, including 5 engineers in multiple-disciplines of engineering, 5 production engineers & 56 well trained workers & quality control team. Our inhouse rapid prototyping & low volume manufacturing service are available for miscellaneous engineering, displaying & promoting, functional testing & production demands.



3D Reviewing
Our engineering team analyze 3D drawings for debugging, and give suggestions based on our in-depth know-how in China rapid prototyping practice, as well as mass production.
Vacuum casting benefits the soonest possibilities & maximum flexibilities from prototype to production, is ideal for low volume manufacturing.
CNC machining bring high precision and robust part manufacturing solutions. It is the optimal solution to vacuum casting master model, especially when there is tight tolerance.



High volume mass production steel tooling for large scale plastic parts, various options available for materials, colors, surface finishing, overmolding…etc., we help customers in injection molding after the prototypes are confirmed.
3D printing or additive manufacturing is the process of construction from digital files in computer to real. It is creating object by laying down successive layers of different materials, such as plastic, liquid and powder gains.
Rapid Prototyping
Prototypes are helpful in verifying mechanical designs & problem spotting, especially for the functional work abilities checking (functional prototypes) before launching out; or for the marketing promotions like kicker starter campaign. We are sampling high quality objects through top-line service of rapid prototyping.

How to work with us?
Here for your reference the working flow of rapid prototyping & low volume manufacturing process
Either for a single prototype casting, or small series manufacturing, or even at the beginning of a new project, feel free to reach out for advise from China pioneered manufacturer!
a. Reach out for advice.
Once you finished the 3D drawings (preferred to be in step format), feel free to reach out for a brief consulting.
b. Paper works like NDA.
We keep customers' files confidently, and for inner usage only. NDA (non-disclosure agreement) is prepared prior to going ahead at any time。.
c. 3D reviewing & refining
Our mechanical engineering team will working together with customers to check all details & work abilities, as well as 3D drawing amendment. We will also confirm the materials, qty, colors & surface finishing at this time.
d. Prototype casting
Making the prototypes by CNC machining, 3D printing or metal fabrication upon each specific application. Pay attention to all details to get high-quality prototypes.
e. Receiving prototypes & go next step to low volume manufacturing, or injection molding for large scale production
customers receive prototypes, verify designs and go ahead for small series (small lot production) by vacuum casting (preferred), 3D printing and CNC machining; or go with injection molding for mass production.

Advantages of working with us!
We take pride in the goodwill through years of hard works & customer-centered service for rapid prototyping & small series production.
