How We Work for You?

When we receive customers' requirments for their projects via email, phone, online message, website online form, etc, we will provide a preliminary evaluation according customers' requirements on our exsiting solution. If Our exsiting solution is not work, we support to design and develop a new solution for customers. All inquiries will be replied within 15 hours. To provide the proper solution to customer, Customer might need to offer imformation: The project's situation, including the process,time plan for launch, mass production plan,etc. Your product's work condition: For one cycle, how long it works? how long it stop? how long it works? How long it stops between cycle and cycle? How many cycles it work per day? Will it hit stall during operation? Motor related requirements: demension, voltage, load speed, load torque, shaft, etc. The special requirements of the motor: high temperature resistance, waterproof,lifetime, etc. The time plan for project, annual quantity of motor product,etc

How We Work for You?

Our Support Process


Quality Assurance

Quality Assurance


We have the Strict quality control system, from material procurement, material testing, production, semi-finished product testing, Production progress control, finished product testing.
Certifications Support

Certifications Support


We provide professional certification/compliance test for customers.
Solve Issue during costomer testing

Solve Issue during costomer testing


When customer test samples on their products, if it has some issues, we will analyse the issue and provide solution. And provide some suggestions.

Requirements discussion

Requirements discussion


To ensure providing the best solution of DC gear motor, the sales engineers should discuss with customer some important infomation including:

  • The installation demension for DC gear motor
  • The parameter for DC gear motor includes operation load speed, operation load torque, voltage, output load current,stall torque, stall current, work cycle, working condition, noise level, lifetime,Electromagnetic shielding, etc
  • The certification requirements, such as CE, ROHS, SGS, TEACH.
  • The target cost and project plan.
Project Evaluation

Project Evaluation


According customer’s requirments for DC gear motor and other information of project, our R&D team analyst and evaluate the project. And to confirm provide our exsiting solution or build a new solution. If to design a new DC gear motor, DONGMING design team will provide the project evaluation report for the development time, mold cost and risk.

Prototype sample manufacturing

Prototype sample manufacturing


Depending on your requirements, After our team evaluation and providing the solution for you, we will customize the prototype samples for your project. Our engineers will make 2D/3D drawing to you.

Sample performance test

Sample performance test


After the samples completed, we will make some basic test with our dynamometer. To test the load speed, load torque, voltage, current. To Automatically Generate graphs for these data. Or lifetime test if customer have the requirement for cycle test.

Small batch production and mass production

Small batch production and mass production


After strict cycle test, if the prototype sample operates well and it meet customers’ requirements. We suggest customer start a small batch production to test market and abtain the market feedback. Launching small batch to test market is huge imptortant before bulk production.

Delivery and after-sales service

Delivery and after-sales service


Manage the product lines to ensure the lead time of batch delivery. When all products are completed in mass production, we will proceed the delivery as customer's requirements.
