Manufacturing Process with Apollo PP EBM
The manufacturing process for PP food and cosmetic containers using Apollo’s EBM machines involves several key steps, each of which is critical for ensuring product quality and hygiene:
Step 1: Preparation of PP Resin
The first step in the manufacturing process is to prepare the PP resin. PP resin pellets are loaded into the machine’s hopper, which feeds the extruder. The pellets are typically dried before processing to remove any moisture, which can affect the quality of the final product.
Apollo provides guidance on PP resin selection and preparation, helping customers choose the right PP grade for their specific application. The company also offers material testing services to ensure that the resin meets the required quality standards.
Step 2: Extrusion of Molten PP
Once the resin is prepared, the extruder heats and melts the PP pellets to their melting point. The rotating screw inside the extruder pushes the molten PP forward through the barrel, where it is further mixed and homogenized. The molten PP is then forced through the die head, which shapes the plastic into a continuous tube known as a parison.
Apollo’s extruders are designed for processing PP with ease, ensuring smooth extrusion and consistent parison quality. The company uses high-torque motors and precise temperature control systems to ensure that the PP is heated to the correct temperature for optimal processing.
Step 3: Parison Formation
The die head shapes the molten PP into a parison, which is a tube of molten plastic that will be inflated into the container shape. Apollo’s die heads are designed to minimize material waste and ensure uniform wall thickness throughout the parison, which is essential for maintaining the structural integrity of the container.
The parison thickness can be adjusted using the machine’s automatic parison programming system, allowing operators to control the thickness of the container walls. This is important for ensuring that the container can withstand the pressure of the product, as well as for optimizing material usage.
Step 4: Mold Closing
Once the parison reaches the correct length, the mold closes around it. The clamping unit applies sufficient force to hold the mold closed tightly, ensuring that the parison is sealed properly to prevent air from escaping during inflation.
Apollo’s clamping units are designed with high-precision mold alignment systems that ensure the mold halves fit together perfectly. This helps reduce the risk of parison defects and improves product quality.
Step 5: Blowing the Parison
After the mold has closed, the blow pin injects compressed air into the parison, causing it to expand and conform to the shape of the mold. The air pressure is carefully controlled to ensure that the parison expands evenly, avoiding wrinkles or thin spots.
Apollo’s blow pins are designed to deliver air at a consistent pressure, ensuring uniform inflation of the parison. The company also offers automatic blow pin positioning systems that help improve production efficiency and reduce setup time.
Step 6: Cooling the Container
Once the parison has been inflated, the cooling system activates to solidify the PP container. Water or air is circulated around the mold, reducing the temperature of the plastic and allowing it to retain its shape after ejection.
Apollo’s cooling systems are designed to provide efficient and uniform cooling, reducing cycle time and improving product quality. The company uses advanced temperature control systems to ensure that the mold temperature remains consistent throughout the production process.
Step 7: Ejecting the Container
After the container has cooled sufficiently, the mold opens, and the ejection system removes the finished product from the mold. The container is then conveyed to a packaging station or stored for further processing.
Apollo’s ejection systems are designed to minimize damage to the container during ejection, ensuring that the product remains intact and free from defects.
