TECHNOLOGIES
We provide advanced rigid plastic packaging manufacturing solutions in the Philippines, serving food, beverage, personal care, pharmaceutical, and industrial sectors.
INJECTION STRETCH BLOW MOULDING (ISBM) – Step 1
Preforms are first produced in the injection-moulding process. Directly afterward, the tempered and still soft preform is stretched and blown to the final shape in the blow cavity. In 1-step moulding, these two steps are carried out in one machine. These bottles have a clearly distinguishable injection point at their base.
INJECTION STRETCH BLOW MOULDING (ISBM) – STEP 2
Preforms are first produced in the injection-moulding process. In an independent, second step, known as stretch blow moulding, the preforms are reheated and stretch-blown to the final shape in the blow cavity. These bottle have a clearly distinguishable injection point at their base.
INJECTION MOULDING (IM)
Injection moulding is the high-pressure injection of the raw material into a mould, which shapes the polymer into the desired form.
EXTRUSION BLOW MOULDING (EBM)
In extrusion blow moulding, the material is extruded into a parison. The parison is then clamped into a mold and blown into its final shape. A typical feature of packaging made using this technology is the welding seam at the base of the bottle.
INJECTION BLOW MOULDING (IBM)
For smaller containers with high-quality standards, TPAC uses 1-step injection blow molding process at selected locations. In this process, a preform is first produced, which is then immediately passed to a molding tool and blown into the final shape.
