Buying a dosing machine is not like buying a spare part. Whether it runs stably once installed depends on three things: the right model, correctly calibrated gear settings, and an operator who knows the machine. Here is what we do between your first enquiry and your first production run.
Three facts settle the model choice: the resin grades you run, throughput per machine in kg/h, and how many powders you dose at once. Send them by email or through the form.
Send the resin and color powder you actually run. We test on your material and send you the measured data. This step is free of charge.
Model and price come after the trial results, not before. If your process needs a different configuration, you hear it at this stage — not after the unit is mounted.
The unit mounts above the injection molding machine hopper; the interface dimensions are confirmed on site. Installation scheduling depends on machine count and whether you stop production.
Operators learn two things: how to set recipe gear positions, and how to purge for a color changeover. We spend most of the time on one rule — a new resin grade requires re-calibration. That is where problems start if it is not understood.
This is not a selling point. It is a condition of use. If it is not explained, the first resin change will look like a machine fault.
Every recipe is tied to a specific resin grade. The metering chamber is volumetric: the volume is fixed, so the mass per dose varies with the bulk density of the resin — roughly 1.3 kg per chamber for PP, 1.7 kg for PS. Run PP and then PS at the same gear position and the powder dose is unchanged while the resin charge is heavier, so the color comes out visibly lighter. A new resin grade requires re-calibration. This is inherent to volumetric dosing, not a malfunction. Training covers it, and every recipe sheet states the resin grade it was calibrated against.
At very low let-down ratios the correct approach is a diffusion powder carrier with the gear count raised to 100 — not forcing the count down to 10. Below a certain gear count the per-dose mass is too small to stay consistent.
DualMode™ runs either color powder or masterbatch: you change the component set, not the machine. Masterbatch and color powder use different metering gears — fit the matching gear set and re-calibrate after switching.
5th Generation: 1 minute to swap the chamber, under 5 minutes for a full purge. 4th Generation: 10 minutes. The mixing chamber is sealed and leaves no residual material, so there is never a batch of pre-mixed resin sitting in the vessel at changeover.
Current after-sales terms are stated below. Remaining specifics — wear-part definitions and training scheduling — follow the signed sales contract.
From the date of acceptance. Faults or failures caused by the product itself are repaired or replaced free of charge within the warranty period. Out-of-warranty repairs are charged at cost.
Most issues can be identified by phone or video without waiting for an engineer on site. We dispatch only when remote diagnosis cannot resolve it.
Common wear parts are held in stock. Powder hoppers, metering gears and mixing chambers are model-specific — quote your model and serial information and we match the correct part.
| Region | Response | On site |
|---|---|---|
| Jiangsu / Zhejiang / Shanghai | within 24 h | within 4 h |
| Other regions in China | within 24 h | within 48 h |
| Export markets | within 24 h | by agreement |
Times run from the moment you report a fault and it is confirmed. Most issues are solved remotely with no site visit; the table covers the cases that require an engineer. Public holidays and force majeure — severe weather, traffic restrictions — extend these times. Contractual terms follow the signed version. On-site response in export markets depends on distance and local service arrangements and is agreed per contract.
Source spare parts through official channels. Powder hoppers, metering gears and mixing chambers are matched to the machine model — the wrong part will not fit. When ordering, quote your model and serial information. Service line 18989669291.
The practical questions an importer asks before anything else. Where we have a measured figure, it is below. Where we do not yet have written confirmation, the line says so rather than carrying a number we cannot stand behind — ask us and we will confirm it for your order.
| Item | Specification |
|---|---|
| Supply voltage | AC 220 V, 2P + PE, 50 Hz (single phase) |
| 110 V / 60 Hz version | Ask before ordering — not a configuration we can confirm from stock documentation. Tell us your supply and we will answer for your order. |
| Power consumption | 240 W (5th Gen Standard) · 280 W (5th Gen Dual-Powder) · 180 W (4th Gen Standard) · 430 W (Large) |
| Compressed air | 0.5–0.6 MPa, dry and oil-free |
| Machine dimensions | 343 × 294 × 941 mm (5th Gen Standard) · 541 × 432 × 1150 mm (Large) |

| Packed dimensions | 750 × 480 × 440 mm (5th Gen Standard) · 1000 × 400 × 320 mm (4th Gen Standard) |
| Warranty | 12 months from acceptance |
| CE / RoHS marking | Not currently held. — We would rather tell you now than at the port. If your market requires CE marking, say so when you enquire and we will tell you where that stands before you commit to anything. |
| Lead time | Quoted per order — it depends on configuration and the current build queue, so we give you a date against your actual order rather than a figure here. |
| Trade terms & port | Quoted per order |
| English documentation | Ask before ordering — tell us what you need (manual, nameplate, controller interface) and we will confirm what can be supplied in English. |
Why some lines above say “ask” instead of giving a number. It would be easy to write “CE certified, 4–6 weeks, FOB Ningbo” on a web page. We publish only what we can put in a contract and produce the paperwork for. We do not hold CE marking today, and lead time depends on configuration and the current build queue — so you get a date against your actual order rather than a figure copied off a brochure. If any of these decides your purchase, ask, and you will get a straight answer.
Once your material arrives and the data is in, the model and the price follow from it. This step is free of charge.
