Designed around PET plasticizing and preform molds
Each PET preform injection machine is based on the M8SII platform and configured for water, carbonated-beverage, edible-oil, wide-mouth and large-format preforms.
01
25:1 PET screw
A dedicated screw ratio supports PET plasticizing and preform transparency.
02
Optimized injection unit
Linear guides balance movement and improve injection stability.
03
Twin-cylinder balance
Twin injection cylinders reduce return resistance during high-pressure injection.
04
Rigid clamping unit
The clamping structure is designed for stable movement and broad mold accommodation.
05
Extended ejection
Longer stroke and higher ejector force support long and multi-cavity preform molds.
06
Closed-loop lubrication
Quantitative lubrication and fixed-point delivery reduce oil loss and support reliability.
MACHINE & MOLD INTERFACE
Review the complete mold interface
The machine range can be configured for 16-, 24-, 32-, 48-, 64-, 72- and 96-cavity preform molds, plus 28 mm neck, wide-mouth and large-format projects. Final model compatibility depends on more than clamping force.

PET Preform Cycle Time & Production Output
There is no single cycle time for every PET project. Stable hourly output is estimated from the confirmed preform, mold, cooling system, machine recovery and handling sequence.
Cavity count
More cavities can increase hourly output, but also change shot size, mold size, cooling demand and investment.
Preform weight
Heavier preforms require more injection capacity, plasticizing capacity and cooling time.
Cooling window
Mold design, chilled-water temperature and flow strongly influence the stable cycle.
Take-out and handling
Robot motion and downstream transfer must keep pace without damaging hot preforms.
Estimate hourly output
Preforms per hour = cavities × 3,600 ÷ cycle time in seconds, before downtime and rejects.
Example from the reference table: HMD430PET with a 72-cavity mold at a 9.9 s cycle gives 72 × 3,600 ÷ 9.9 ≈ 26,180 preforms per hour. Apply your own uptime and reject rate to plan daily output.
PET RESIN DRYING
PET Resin Drying Before Injection
PET absorbs moisture from the air. The resin must be dehumidified, dried and conveyed under controlled conditions before it reaches the screw. Final settings must follow the resin supplier data and verified production conditions.
Confirm the bottle-grade PET resin and supplier drying windowMatch dryer capacity to material consumption and residence timeUse closed conveying to limit contamination and moisture regainVerify preform appearance and process quality during the trial
Read the PET processing guide COOLING & AUXILIARIES
Cooling & Auxiliary Equipment for PET Preforms
Auxiliary equipment is sized as part of the production cell. The final list depends on resin consumption, mold cooling demand, color dosing, compressed air, take-out and site conditions.
Resin preparation
A three-in-one dehumidifying, drying and loading system prepares PET before plasticizing.
Mold cooling
The industrial water chiller is matched to mold circuits, water temperature, flow and heat load.
Compressed air
Plant air supports the specified machine, valve and automation requirements.
Dosing and take-out
Masterbatch dosing and robot handling are selected around color control and the production layout.
COMPLETE LINE

Questions to answer before quotation
Use these answers to prepare the technical information needed for an accurate recommendation.
Which machine size do I need for my preform weight and cavity count?
Multiply the preform weight by the cavity count to get the shot requirement, check it against the PET shot weight of each model, and check the mold against tie-bar spacing and mold thickness. In customer mold trials, the HMD320PET has run 48 × 15.2 g and 72 × 13 g molds, the HMD430PET 72 × 16.5 g and the HMD500PET 96 × 15.2 g. Send your preform and mold data for a model recommendation.
How many cavities can each model run?
It depends on preform weight and mold size. The reference configurations show 32 cavities on the HMD268PET, up to 72 cavities on the HMD320PET and HMD430PET, and 96 cavities on the HMD500PET. Heavier preforms need more shot capacity per cavity: the HMD320PET runs 24 cavities of 85 g and 12 cavities of 135 g.
What information is required to select a PET preform machine?
Send the preform weight and drawing, neck finish, mold cavity count or target output, resin, voltage and available plant utilities. Unknown values can be reviewed together.
What decides PET preform cycle time and hourly output?
Preform weight and wall thickness, cavity count, mold cooling, plasticizing recovery and take-out decide the stable cycle. Hourly output = cavities × 3,600 ÷ cycle time in seconds, before downtime and rejects. For example, 72 cavities at a 9.9 s cycle gives about 26,180 preforms per hour.
What affects PET preform injection molding machine price, and what is in the quotation?
Price depends on the model and injection unit, cavity count and mold interface, auxiliaries, automation, utilities, logistics and service scope. Prices are quoted FOB Ningbo for each project. Auxiliary equipment, installation and training are optional and quoted per project, and the quotation lists every item included.
Can my existing PET preform mold be used?
Yes, after checking mold dimensions, platen and tie-bar fit, injection requirement, ejector, hot runner, cooling and controls.
Can HWAMDA supply the machine and mold together?
Yes. HWAMDA can include the PET preform mold in the project scope and verify the machine and mold together in a combined trial.
Which auxiliary equipment is required?
The final list depends on resin and output. Drying and dehumidifying, conveying, mold cooling, compressed air and take-out are normally reviewed. All auxiliary equipment is optional and quoted per project.
Why must PET resin be dried before injection molding?
PET absorbs moisture from the air. Wet PET loses viscosity during melting, which affects preform clarity and strength, so the resin is dehumidified and dried to the resin supplier’s data before it reaches the screw.
Can HWAMDA configure a complete PET preform production system?
Yes. HWAMDA can coordinate the machine with the mold, resin preparation, cooling, dosing, compressed air and take-out equipment according to the confirmed project scope.
What is the delivery time for a PET preform machine?
Machine lead time is 60 working days. Mold, auxiliary equipment and shipping times are confirmed in the quotation for your project.
Does this machine also make the finished bottle?
No. This machine injection-molds the preform. A separate blowing machine reheats and blows the preform into the final bottle.
Is a HWAMDA PET preform machine available for sale?
Yes. HWAMDA supplies new PET preform machines for international projects, configured to the preform, mold, output target and plant utilities.
