Product Engineering*

Transformed from factory to sourcing company since 2010, the most obvious advantage of Ruizhi sourcing compared with other sourcing companies is that we have the ability to provide product engineering services (such as die casting, metal stamping, injection molding to surface treatment). That means, we can not only help you with sourcing, but we can also turn ideas into reality with our product engineering services. Most sourcing companies know how to source, that’s not strange, but a truly professional sourcing company needs to know how to produce.


You comes a good idea about a product that hasn’t been shown in the market or even hasn’t been produced. How can an inexperienced client and a sourcing team without product engineering services produce it? Well, with the help of us, all your ideas can be lit up. We comprehend the factory process better than the client and comprehend the client's needs better than the factory.


Get your ideas - understand your need - design the drawings - discuss the details - build the mold - produce the sample, confirm the final version, and then put it into production. Factory inspections, technology verification, quality testing, sample delivery, cost analysis, logistics, and after-sales service, we treat every process attentively. 

The end-to-end flow is as below:



01

Your creative drawing

Usually, product engineering services are based on your ideas and concepts, to be more specific, drawings. As the core of product engineering, the importance of drawing is self-evident. 


We collects your drawings, product IDs, or sketches to comprehend your thoughts and creativity better. 

 


Creative-Drawing
02

3D mechanical design

After the drawings were constantly discussed and improved by us, we will begin to conduct the 3D modeling. 


The 3D modeling will design according to manuscripts, in the meantime, the details would be negotiated over and over again until both sides feel satisfactory. 


3D Mechanical design
03

Prototyping

In digital product engineering services, prototyping is also a vital part. Proofing needs to be done based on the material of the components and parts. 


Then we will assemble the samples, find out issues of the samples, and communicate with you for in-depth adjustments. We will proof and proof again until you are satisfied. 


Prototyping
04

Details confirmation

In order to achieve the demands from samples to mass production, we need to evaluate the performance matching between product components, the coordination rationality of space design, the structural relationship of each part of the whole system, and perform continuous adjustment of sample data and assemble so as to achieve final mass production requirements.


Details Confirmation
05

Pilot Run

After the sample is confirmed, small batch trial production can be arranged. The overall production process, sampling inspection, and quality experiment can be checked whether it can meet the mass production through trial production.


The process from die casting, metal stamping and injection molding to surface treatment of each part should be verified one by one.

06

Production process control

Through small batch trial production, engineers begin to make each process operating procedures and quality sampling test procedures.

Sourcing the best partners for different components

Just like Indiegogo and Kickstarter we are committed to helping you ‘touch dreams’ with our comprehensive product engineering services. And a good partner is necessary for satisfactory cooperation. The strict criteria will be used to integrate the most suitable suppliers for each component or raw material. 


Sourcing the best partners

Price optimization

The final step of product engineering services is price optimizatioin. A comprehensive analysis will be done of all costs, including material cost, loss cost, packaging cost, transportation cost of each component, all kinds of taxes that need to be charged, etc. Strive to enable you to customize the most suitable product at the most competitive price.
