BLOW BOLDING PRODUCT PRODUCING PROCESSING
Blow molding products are widely used in several of industries. The tubular plastic parison obtained by extruding the thermoplastic resin is placed in the split mold while it is hot (or heated to a softened state). It is attached to the inner wall of the mold, and after cooling and demoulding, various of hollow products are obtained.
The extrusion blow molding process consists of 5 steps:
In the past two years, we have been researching and designing automation production to assist blow molding machines to complete automated production systems. This system starts working from the machine's mold opening, and can accurately and automatically complete a series of post-processing procedures such as taking products out of the machine → removing leftovers →trimming→ jig shaping → cooling → drilling→stacking.
We currently have four automated production systems, which can quickly and accurately complete many processes that require human labor, helping us save labor costs and the current most serious labor shortage problem, and further ensure the delivery timeline. These automation system will be provided free of charge if the product can reach MOQ.
BLOW MOLDED PRODUCT OEM PROCESSING
● Product quality requirements/unit expectations
● Learn about the finished product
● Asking for drawings or samples
● Wall Thickness Requirements
a. If there are no drawings and samples, rough quoting can be done with the above information. We can offer help for free to assist you finish 3D/CAD drawing to get all the specifications.
b. If you have drawings and samples, you can send the drawings directly to us to get an accurate quote. Please help to export files in STEP (.stp), PARASOLID (.x_t), IGES (.igs) and similar formats. If you already have a design, you can email it to us along with any other requirements you want to include in your request for quote (RFQ).
If our initial pricing matches your expectations, it's time to move on to the next step.
◈ Mold design and Building
Before starting building molds, we will provide DFM (Design for Manufacturability) for both injection mold products and blowing mold products.
The below information will be listed in it:
Mold and product information
Part line location
Blowing pin location
Material Shrinkage rate
Venting holes location
To make sure both sides are in the same page, we will start to prepare the mold drawing after DFM has been confirmed.
We need another 35 days to finish the tooling processing. There are the blow molding processing tooling material we are using, 718H, 738H, P20, #45, #50 steel etc.. Some of our customer who made auto parts will use higher grade of steel to make the mold.
We also accept existing molds removed from other factory for producing, just need to confirm their molds could match with our machines before transferring.
◈ Proofing stage
It's time to move forward to the next step-proofing.
Proofing is something that we look forward to and excited about; it can finally witness our previous efforts. Generally go through the following proofing process:
The products are allowed to start mass production after sample been approved. Our company has a dedicated system and production manager responsible for the schedule of all blow molding products. Please check our "Production Processing Chart" to get the detailed information about how to producing and control the quality.
Some of the finished parts can be shipped to the customer directly, but some of them need to be installed in our factory. There are 4 lines over 150 workers available to assemble kinds of complex unit. Our success in assembly is derived from our ability to look at an assembly operation and lean engineer it to streamline the process, often drastically decreasing the amount of time it takes to complete an order. We do not just assemble; we solve our customers' headaches while delivering orders on time.
All the above efforts are aimed at being able to deliver goods on time and efficiently. We can load over 200 containers each month.
