Injection Molding
Precision Filling Stage
To prepare the material for this step, we melt the PVC pellets into a liquid form. The molten PVC material is fed onto our injection molding machine. This process is done within minutes since the material is injected onto the molds at incredible speed, building up pressure within the mold will secure the liquid PVC. Applying the proper injection pressure prevents any defect on the PVC trunking and conduit product.
Solid Pressure Containment
After the injection process, we continue to apply pressure onto the PVC product to increase its plastic density and allow it to hold its form. During this process, we ensure our PVC trunking and conduit products have superior strength.
Controlled Cooling
Almost immediately after the injection process, we cool down the formed PVC product from the molten plastic. This process allows the material to retain its shape as it shrinks and solidifies in its appropriate form.
Logo Carving
Engraved logos and designs add a fantastic texture to your pvc-u trunking products, which have a higher chance of leaving a lasting impression on your audience. With diverse molds, our designers and manufacturers can create distinctive designs on the surface of your plastic products efficiently and with precision.
Send us your logo and the letter of authorization for using the logo, let Budgie’s seasoned design team assist you in creating impactful logo carving.
Efficient Ejection
After the material has cooled for a specific period, the injection molding machine opens the clamped molds and pushes the product out from the cavity. A sufficient amount of force is used to efficiently remove the product from the mold without breaking it. Through our ejection process, we avoid creating cracks and other defects on the product.
Factors That Leads to a Successful
Injection Molding Procedure
Injection Pressure
A proper among of pressure is applied during the injection process to ensure a smooth filling of the material, avoiding flash and sink mark defects.
Injection Time
The material is injected at a short period of time than the cooling process. With the proper injection time, our PVC products achieve a better surface appearance.
Holding Pressure
Preventing shrinkage marks requires a proper hold pressure of 85% near the last part of our injection molding process. We also ensure the mold cavity is full to compensate for the shrinkage rate.
Injection Temperature
We adjust the injection temperature to melt the plastic at the desired pace. Properly adjusting the temperature can prevent bubbles to form.
Clamping Force
By using an appropriate clamp force, we prevent the molten material from leaking out of the mold and create a flash defect.
Back Pressure
Utilizing a high back pressure can achieve a proper dispersion of pigment and plastic melting rate of the material.
We are invested in your brand’s progress.
See how we can propel your brand to unparalleled heights.
