HDPE Shampoo Flip Cap Injection Molding Machine
An injection molding machine configured for plastic shampoo flip-top caps in HDPE. A hot-runner, multi-cavity mould fills many closures each shot while the living hinge forms cleanly for repeated flip-open use.
Overview
Flip caps demand a precise hinge and a leak-tight seal, so this machine pairs servo or electric drive with a hot-runner tool that injects many cavities at once for high closure output. The hot runner cuts cold-runner scrap and keeps fill balanced across cavities, giving uniform hinges and sealing surfaces from cap to cap. Servo or all-electric operation lowers power draw on these short, fast cycles.
Key features
- Hot-runner mould fills many flip caps per shot
- Forms clean living hinges for repeated opening
- Servo or electric drive for fast cap cycles
- Balanced fill keeps seal surfaces consistent
Application
HDPE flip-top and snap closures for shampoo, conditioner, lotion and personal-care bottles on cosmetic filling lines.

One machine covers a range of sizes: you only change the mould to make a different product. The machine must be selected according to the LARGEST product you plan to make — running a small product on a large machine is possible, but you lose some efficiency and some material. Send us your smallest and your largest product (size and weight) and we will confirm whether one machine is enough.
Flip top cap moulds are one of the three kinds of tooling we do best. Order the flip top cap mould with this machine and we make it in our own workshop, then ship machine and mould as one set, tested and tuned together. The mould itself takes 40–60 days from approved drawings. Send your part drawing and we quote the machine together with the mould.
Each machine is configured to your container; the final specification is written into your quotation.
