Ten M8-SP6 models from 2,700 to 6,500 kN
Compare the range, then open a model for its mold space and the two injection options. HMD380, HMD420, HMD458 and HMD480 share one injection unit; choose between them by clamping force, tie-bar spacing and mold space.
Shot weight and injection speed use the PS reference; each model lists two screw options.

PRODUCTION EXAMPLES
Recorded SP6 production cycles
Examples recorded on running HMD458M8-SP6 and HMD550M8-SP6 machines. Your cycle depends on the product, resin, mold and cooling, so we confirm it for your project.
| Machine | Product | Cavities | Part weight | Cycle | Output/hour (calculated) |
|---|---|---|---|---|---|
| HMD458M8-SP6 | 650 ml rectangular food container | 8 | 10.5 g | 3.3 s | 8,700 |
| HMD458M8-SP6 | 1,250 ml food container | 6 | — | 4.3 s | 5,000 |
| HMD458M8-SP6 | 1,000 ml square food container | 6 | — | 4.0 s | 5,400 |
| HMD550M8-SP6 | Square clear container | 12 | — | 5 s | 8,640 |
| HMD458M8-SP6 | Blueberry punnet | 8 | — | 10 s | 2,880 |
From cycle to output
Hourly output = cavities × 3,600 ÷ cycle time in seconds. For the first example: 8 × 3,600 ÷ 3.3 ≈ 8,700 containers per hour before planned stops and quality checks.

WHAT MAKES THE SP6 HIGH-SPEED
Built for short thin-wall cycles
Catalogue data for the sixth-generation M8-SP6. Improvements are stated against the previous HWAMDA generation.
Faster injection response
Single-cylinder injection on the main models, a twin-cylinder balanced injection seat and a low-inertia, high-response servo motor. Injection speed is up 15% and response up 20%.
Rigid clamping
Platen deformation reduced by 15% and maximum stress by 10%. Alloy-steel tie bars with special heat treatment, and graphite self-lubricating steel and copper bushes.
Repeatable mold movement
A closed-loop proportional valve controls opening and closing. The repeat opening position reaches ±0.2 mm, so the robot picks parts accurately at speed.
Plasticizing during the cycle
Electric plasticizing is standard on every model, with a screw designed for packaging resins. A pre-opening function shortens the time between cooling and part removal.
Control and factory connection
15-inch touch screen with storage for 1,000 mold settings
Speed fluctuation below ±5 rpm at full load; pressure stability improved by about 15%
Barrel temperature reaches a stable state 50% faster
MES interface standard on every model: OPC-UA, MQTT and MODBUS
Communication ports: RS-485, USB, CANopen and EtherCAT

HIGH-SPEED VS STANDARD
Choose the performance your product needs
Not every molded product requires a high-speed machine. Compare the filling window and complete production requirement before selecting a machine family.
| Requirement | High-speed review | Standard-machine review |
|---|---|---|
| Filling & response | Demanding thin-section filling profile | Filling profile within the proposed machine’s capability |
| Mold & cooling | Balance filling and release with the short-cycle target | Match the mold and cooling to the required production rate |
| Automation | Coordinate handling or IML with the full cycle | Select handling according to the actual part and output task |

BUYER QUESTIONS
High-speed machine selection FAQ
What is the difference between a high-speed and standard injection molding machine?
Selection depends on the filling window, machine response, plasticizing recovery and coordinated mold movements. A standard machine can be the right choice when it meets the product and production requirements.
Why does thin-wall molding require faster machine response?
A thin flow section can leave less time to fill the cavity before the melt cools. The machine must establish and control the required filling profile with the chosen material and mold.
How do wall thickness and flow length affect machine selection?
Review them together with resin grade, gate location and cavity geometry. A longer flow path through a thin section can increase filling demands; wall thickness alone does not define a machine size.
How does cavity count affect machine configuration?
More cavities change the total shot requirement, projected area, filling balance, cooling load and handling task. Review the complete mold rather than assigning a model from cavity count alone.
What mold requirements matter for high-speed production?
Check mold dimensions and mounting, projected area, filling balance, runners and gates, cooling, venting, ejection and robot access. Physical fit alone is not enough.
What determines cycle time?
Material, part geometry, filling and holding, cooling, mold movement, ejection and robot or IML timing work together. Validate the complete cycle against part quality rather than using one universal cycle figure.
Can the machine be integrated with IML automation?
HWAMDA can review machine signals, mold opening, label placement and take-out timing with the IML configuration. The agreed interfaces and sequence are checked for the project.
Can HWAMDA match a machine to an existing mold?
Send the mold drawing, dimensions, weight, cavity and injection requirements, cooling connections and ejector details. The review covers both installation fit and production requirements.
What information is needed to choose a high-speed machine?
Start with a product photo or drawing, material if known, dimensions, weight, wall thickness and target output. Include available mold and automation details; you do not need to know the machine tonnage.
What determines high-speed injection molding machine price?
Machine size, injection option, controls, automation and auxiliary scope affect the quotation. Prices are quoted FOB Ningbo for the configuration your product needs, so proposals can be compared on the same basis.
What is the difference between HMD380, HMD420, HMD458 and HMD480?
The four models share the same injection unit (55 or 57 mm screw, 432–465 g PS). They differ in clamping force, tie-bar spacing, platen size and mold space, so the choice follows your mold size and projected area.
What is the delivery time for an SP6 machine?
Machine delivery is 60 working days. Molds, automation and auxiliary equipment are scheduled in the same project quotation when you order them together.
What clamping force do I need for a thin-wall food container?
Calculate from projected area and cavity pressure, then confirm the machine and mold together. Use the tonnage calculator for an initial estimate and send the product and mold data for review.
Which SP6 model suits an 8-cavity 650 ml container?
The recorded example uses an HMD458M8-SP6 with an 8-cavity mold and a 3.3 s cycle. Confirm the final model against your mold dimensions, shot weight and target output.
What injection speed does the SP6 reach?
Injection speed is 419–637 mm/s depending on the model and screw option. Shot weight and speed use the PS reference.
