HWAMDA
Service scope
An injection molding machine earns its value over many years of production. HWAMDA supports customers from installation through daily operation, with service built around the machine, the mold and the people running them.
- Installation and commissioning
- Positioning, leveling, utility connection, first start-up, hydraulic and electrical checks, and setting up the first production parameters with your mold.
- Operator and maintenance training
- Hands-on training on controller operation, mold setting, process adjustment, safety functions and routine maintenance tasks.
- Remote technical support
- Diagnosis by email, video call or messaging using photos, videos, alarm screens and parameter pages from the machine.
- Troubleshooting
- Structured fault finding for hydraulic, electrical, control and process problems, from alarm codes to part defects.
- Spare parts supply
- Wear parts, electrical components, hydraulic components, heaters and sensors identified by machine model and serial number.
- Maintenance guidance
- Recommended maintenance intervals, oil and filter care, lubrication and inspection routines suited to your operating hours.
What to send with a service or spare parts request
Most service questions are solved faster when the first message contains the right information. Collect the items below before you contact us.
| Information | Why it helps |
|---|---|
| Machine model | Identifies the series, clamping unit and injection unit, for example HMD450M8-SII or HMD450FCII. |
| Serial number | Links the request to the exact build, controller version and installed options. |
| Controller type and software version | Shown on the controller screen; needed for parameter and alarm interpretation. |
| Photos and video | Show the fault, the component, leaks, noise or part defects; a short video of the cycle is often the quickest diagnosis. |
| Alarm codes and alarm history | A photo of the alarm page and recent history shows the sequence of events. |
| Part number or nameplate | For spare parts, the part number from the manual or a clear photo of the component nameplate avoids ordering errors. |
| Operating conditions | Mold, material, cycle time and when the problem started help separate machine faults from process issues. |
Recommended spare parts kit
Keeping a basic stock of fast-wearing and critical parts on site reduces downtime. The kit below is a typical starting point for a servo-hydraulic machine; the final list depends on the model, options and number of machines in your plant.
| Category | Typical items | Reason to stock |
|---|---|---|
| Plasticizing | Screw tip, check ring, check seat, nozzle tip | Wear items, especially with filled, recycled or PVC materials |
| Heating | Barrel heater bands, nozzle heater, thermocouples | Common failure points that stop production immediately |
| Hydraulic | Seal kits for injection and clamp cylinders, oil filter elements, suction filter | Seals and filters are routine maintenance parts |
| Electrical | Proximity switches, limit switches, fuses, relays, solid-state relays | Small, inexpensive parts with high downtime cost when missing |
| Safety and motion | Safety door switches, linear transducer or position sensor | Required for safe operation and accurate positioning |
| Lubrication | Lubrication pump filter, distributor blocks, grease nipples | Supports toggle and guide lubrication |
Ask for a model-specific spare parts list when you order the machine so the kit can ship with the equipment.
Injection molding machine components explainedSupport across the machine lifecycle
Service needs change as a machine moves from start-up to years of daily production. Planning support for each stage keeps the machine productive and protects the investment.
| Stage | Typical support | What your team gains |
|---|---|---|
| Before delivery | Utilities list, foundation and layout guidance, recommended spare parts list | A plant that is ready when the machine arrives |
| Installation | Positioning, leveling, connection checks, first start-up, mold setting | A machine running your mold under production conditions |
| Ramp-up | Process optimization, operator coaching, cycle and quality fine-tuning | Stable output and confident operators |
| Daily production | Remote support, troubleshooting, spare parts orders | Short interruptions and quick answers |
| Long-term operation | Maintenance planning, wear part replacement, upgrade discussions | Consistent performance over the machine's life |
Common issues we help diagnose
- Hydraulic oil overheating
- Often caused by insufficient cooling water flow, a fouled oil cooler or high system pressure settings. Oil temperature above about 55 °C shortens seal and oil life.
- Inconsistent shot weight
- Worn check ring, unstable back pressure, wet material or barrel temperature variation are typical causes.
- Heater or temperature alarms
- Usually a failed heater band, thermocouple or solid-state relay; photos of the barrel zone readings speed up diagnosis.
- Mold protection and clamp alarms
- Can come from mold setting, low-pressure protection parameters or position sensor faults.
- Part defects
- Short shots, flash, sink marks and burns are reviewed together with process settings, material and mold condition.
Preventive maintenance support
Planned maintenance prevents most unplanned stops. Typical routines include daily checks of oil level, oil temperature, lubrication and safety doors; monthly checks of heater bands, thermocouples, cooling water flow and hydraulic leaks; and periodic replacement of hydraulic filters and oil based on oil condition and running hours. Many plants keep hydraulic oil cleanliness around NAS 7–9 and oil temperature in the 35–50 °C range.
HWAMDA provides maintenance guidance matched to your machine model and operating pattern, and can help set up a checklist for your maintenance team. The maintenance guide in the resources section explains common routines in more detail.

FAQ
Frequently asked questions
Do you install and commission machines outside China?
Yes. Installation and commissioning support is part of project service, including utility connection checks, start-up and setting up production with your mold. The arrangement is confirmed for each project.
What do I need to order a spare part?
The machine model, serial number and the part number or a clear photo of the component and its nameplate. This allows the correct part to be identified the first time.
Can problems be solved remotely?
Many hydraulic, electrical and process issues can be diagnosed remotely using photos, videos, alarm codes and parameter screens sent by your team.
Which spare parts should I keep in stock?
A typical kit covers screw tip and check ring, nozzle tip, heater bands, thermocouples, seal kits, filters, switches and fuses. Ask for a model-specific list.
Do you train our maintenance staff?
Yes. Training covers routine maintenance, lubrication, hydraulic oil and filter care, electrical checks and basic troubleshooting.
Where can I find service contact details?
Email and WhatsApp contacts for our sales engineers are on the contact page. Include the machine model and serial number in your first message.
