  • 01Received drawings

    First of all we need to receive your 3D drawings (stp step igs iges format) and quote according to your needs such as quantity material surface finish etc.

  • 02Engineering and Process Program

    Before the mold is assembled to the injection molding machine the drawing needs to be programmed so that we can clearly see the process of the material as it enters the mold for further adjustments and modifications.

  • 03CNC Machining Producing

    According to the design drawings it is put into CNC processing and production. Strictly control errors and skilled operators for more than 5 years control the quality.

  • 04Process check

    After the mold is complete it is assembled into the injection molding machine. During the injection process we check that the machine is functioning properly (or not) make some necessary tool adjustments and generate a new sample.

  • 05Post-processing size check

    After the samples are surface treated as specified by the customer they will be checked again for dimensions.

  • 06Surface Finishes

    According to customer requirements choose the surface treatment method. At the same time quality inspection work is carried out.

  • 07Final check

    The last step is to check whether the mold needs to be adjusted according to the analysis of the sample and whether the test sample meets the previous requirements.

  • 08Packaging and Shipping

    After the samples have been tested to meet the preliminary requirements the samples can be packaged and shipped.

What is CNC machining?

  • What is CNC machining?

    CNC is the abbreviation of Computer Numerical Control. CNC machining is any kind of machining process controlled by a computer. Computer automation can manufacture parts faster more accurately and more precisely than parts produced by manual machining better suited to complex geometries. CNC also reduces the amount of manual machining work that would otherwise be done by humans. While they don't machine every part themselves people are critical to the programming and operation of the machinery to ensure that every operation runs smoothly.

  • How does CNC machining work?

    Programs now used for CNC machining are written in G-code and are usually created automatically by CAM software. CAM or Computer Aided Manufacturing software produces G-code for a 3D model for a given tool and workpiece material. This G code controls the CNC machine i.e. the movement of the tool workpiece and any tool changes. It even has commands to turn the coolant and other auxiliary components on or off. CNC machining can be used on a variety of materials the most common being aluminum steel brass ABS Delrin and nylon. But in fact almost any hard material can be CNC machined.

  • About the CNC machining process

    CNC or Computer Numerical Control Machining is a subtractive manufacturing method that uses a combination of computer control and machine tools to remove layers from a stationary material. The desired cuts in the metal are programmed according to the corresponding tools and machines which perform the machining tasks in an automatic manner.

  • Types of CNC Machining

    Depending on the type of part that needs to be machined there are different types of CNC machines that are best for the job. CNC milling uses CNC milling machines that consist of multi-axis systems (3 4 or 5 axes depending on part complexity). CNC turning involves a lathe which usually has 2 axes and uses a circular motion to cut the workpiece. An electrical discharge machine (EDM) uses electric sparks to form a workpiece into the desired shape. Gear hobbing is another machining process used to cut gears splines and sprockets. Other CNC machine types include plasma cutters and water jet cutters.

  • CNC and 3D printing

    CNC machined parts are more functional and generally have superior production quality and finish compared to part manufacturing via additive manufacturing. Therefore CNC machining is often used in the mid to late stages of development when the part is ready for functional accuracy testing.

  • CNC Design Considerations

    While most details such as tooling spindle speed tool type and depth of cut are handled in the machine shop there are some key things you can do when designing your parts not only to make sure they are manufacturable but also to make sure you Develop lean products that won't break the bank.
