Establishing Appropriate Quality Standards for Project Succes

Defining quality standards correctly is a sensitive process, and we will share our expertise in this area to ensure the success of your project.

1. Understand the product

Providing details about the product’s use, how plastic parts are assembled and function in the assembly can help us understand the dimensional and aesthetical requirements.

2. Set the inspection criteria

We will create a 2D drawing, specify all necessary dimensional and geometric tolerances (such as flatness, roundness and concentricity), and define the amount of acceptable bending, warping and distortion.

3. DFM and Mold Flow Analysis

We will conduct a DFM and probably a mold flow analysis to see what issues may arise either on the product side or the mold side. Some issues need attention from the mold design stage.

Frequently Asked Questions​

We understand your requirement and provide quality works.

Do you Provide any kind of Warranty ?

If you find the injection molded parts do not meet the specs or have any quality issues within 3 months of their arrival date, please inform us with pictures indicating those issues. We will send you free replacements at our cost, including possible air freight charges.

What is your MOQ for orders?

There is no MOQ required from us, we take orders from 100 units to 1 million, however, the injection mold itself is kind of expensive. To make your investment worthwhile, we suggest your order quantity should be more than 100, otherwise, you should consider other manufacturing processes.

How do I know I will get the products as I expected?

We will analyze what molding defects may arise before mold production, and take preventive measures.

We will send you detailed QC reports with pictures and videos during production and before shipment, so you know exactly what you will receive prior to shipment.

What is the typical mold life?

A mold can complete from 10,000 shots to 1 million shots, we will choose what mold steel to be used based on your estimation of the quantity. At the same time, if you let us produce the plastic parts, you do not need to worry about the mold life, we will take care of the mold maintenance and renewal, so it is a one-off investment for you.

How do I describe the quality requirements for my products?

It is important that you describe the quality requirements clearly, including the material specs, dimensional tolerances, and visual requirements. If you do not have an engineering background, you can explain to us the application in detail. We will figure it out and list the requirements and specs on a pdf drawing for review. It will be used in manufacturing and QC inspection.
