QA/QC

Undoubtedly, quality is crucial to the success of any manufacturing project. This importance is amplified when it comes to rapid manufacturing, as it requires being done right the first time. At HLH, we employ numerous different quality control measures to ensure your rapid projects are not only completed on time but also meet your specified specifications. Below is a quick snapshot showing the steps involved in manufacturing rapid parts.

Here are several videos demonstrating how HLH addresses the two biggest quality control challenges in rapid manufacturing: Material Identification and Dimensional Accuracy Inspection. How do we know that the materials you specify are the ones we use to manufacture your rapid parts? It begins with a good relationship with RAW material suppliers, but the only certainty is investing in technology that allows us to independently verify them. We also rely on technology when it comes to dimensional accuracy inspection, where high-precision measurements are required.

01 Drawings Received

First, we need to receive your 3D drawings (stp, step, igs, iges formats) and provide a quote based on your requirements (such as quantity, material, surface finish, etc.).

02 Design Review & DFM

Analyzing the drawings to ensure they are suitable for mold production, identifying potential problems that may arise during manufacturing, and adjusting the design for more successful production and reduced costs.

03 Engineering & Process Plan

Before assembling the mold into the injection molding machine, the drawings need to be programmed. This allows us to clearly see the process of material entering the mold, facilitating further adjustments and modifications.

04 In-process Checks

After the mold is made, it is assembled into the injection molding machine. During injection, we will check if the machine is operating normally, make necessary tool adjustments, and produce a new sample T1.

05 Post Process Dimension Checks

After the T1 sample undergoes surface treatment according to the customer's requirements, a dimensional check will be performed again.

06 Final Checks

In the final step, based on the analysis of the T1 sample, we will check if the mold needs adjustment and test whether the T1 sample meets the previous requirements.

07 Packing & Shipping

After the T1 sample has been tested and meets the previous requirements, it can be packaged and shipped.
