Customized process

1. Design and sample making

The packaging process starts by designing the packaging format.

We provide 3D drawings according to your requirement.

After your confirming,we will make the sample mold. The sample mold are divided into two types: plaster mold and wooden mold. It takes 5-7 working days to finish sample making.

After the sample mold is finished, we can make samples according to your requirements for sheets. Commonly used sheets include PVC, PET, PS and PP.

2. Choose mass production mold 

When you place orders after testing samples. At this time, we need to make mass production molds.

Both Cooper mold and Aluminum mold are mass production mold, their main differences are: lifetime, quality and cost.

The cost of mass production mold totally different betweenCooper mold and Aluminum mold.

Generally speaking, if the cost of copper mold is about 150 US dollars, and the cost of aluminum mold is about 1000 US dollars.

In the production process of copper mold, due to material reasons, it is easier to break than aluminum mold, and the product quality is not as stable as that of aluminum mold.

The lifetime of copper mold is about a few years, while the aluminum mold can be well preserved for longer time.


3.Blister thermforming
After completing the mass production mold, we can prepare the production of end blister pack,and we need to use a technology called blister thermoforming.

Blister thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in acoppermold or aluminum mold,and trimmed to create a usable product.


4.Die cut
After thermoforming, we need to make die cut mold according to the size of theblister pack for cutting into a pieces of blister packages or trimming extra materials. Finally, after QC inspection, aperfect blister package is completed.

5. Sheet check

The main job of incoming inspection personnel is to inspect the purchased raw materials and components by sampling, and finally make a judgment on whether the batch of products is acceptable or rejected.

6. Production inspection

As a key element of quality control, product inspection allows on-site verification of product quality at various stages of the production process prior to shipment.

7. Random recheck

It is to randomly select the finished product for re-inspection, and it is a key element to ensure product quality.

8. Storage

Packing, sorting, and stacking the intact products after the quality inspection in the warehouse for storage, pay attention to the humidity of the stored air and potential safety hazards.
