Why Choose Haichen HCK530 for Large Basin Production?
530 Tons of Clamping Force for Large Basin Molds
The HCK530 delivers 5300 kN (530 tons) of clamping force. This makes it ideal for large household basins, laundry tubs, and storage containers. The 870×820 mm tie‑bar spacing fits oversized molds easily. The 850 mm opening stroke ensures smooth demolding of deep‑cavity products. The machine weighs 22 tons, giving it the stability and rigidity needed for high‑volume production.
A large basin injection molding machine must handle the substantial projected area of large basin molds. The HCK530’s platen size of 1270×1220 mm provides plenty of space for oversized molds, ensuring consistent part quality.
Servo Energy Saving – Cut Electricity Costs by 30–50%
Basin products are high‑volume, low‑margin goods. Electricity costs directly affect your per‑unit profit. The HCK530 uses a servo motor drive system that adjusts oil pump flow and speed in real time based on actual demand. During holding pressure and cooling, the motor nearly stops. This saves 30–50% energy compared to traditional fixed‑pump hydraulic machines.
The servo system also lowers hydraulic oil temperature by 8–12°C. This extends oil service intervals from 4,000 to 7,000 operating hours. For a factory running multiple machines 24/7, these savings add up fast.
Optimized Injection Unit for Heavy Basin Parts
Large basins need large shot weights. The HCK530 offers three screw diameter options: 80 mm, 85 mm, and 90 mm. The maximum shot weight (PS) reaches 2518 g. The screw design improves plasticizing capacity and injection speed.
| Parameter | Option A | Option B | Option C |
|---|---|---|---|
| Screw Diameter (mm) | 80 | 85 | 90 |
| Shot Volume (cm³) | 2187 | 2468 | 2767 |
| Shot Weight (PS, g) | 1990 | 2246 | 2518 |
| Injection Pressure (Bar) | 1912 | 1700 | 1510 |
| Injection Rate (cm³/s) | 509 | 574 | 643 |
| Plasticizing Capacity (g/s) | 59 | 70 | 89 |

High‑Rigidity Clamping Unit – Precision and Stability
The HCK530 uses a high‑strength clamping structure for stable, reliable performance. The large platen size of 1270×1220 mm gives you plenty of space for oversized basin molds. The 850 mm opening stroke handles deep‑cavity products with ease. This rigidity delivers consistent part quality and lower scrap rates over the machine’s lifetime.
A plastic basin injection molding machine manufacturer must ensure that the clamping unit can withstand the high injection pressures required for large parts. The HCK530’s double‑cylinder injection design ensures stable, repeatable performance.
Wide Range of Applications
Beyond water basins, the HCK530 suits bath tubs, containers, lids, buckets, and many other plastic products. One machine serves multiple uses, maximizing your equipment investment. A basin making machine that offers this versatility delivers better return on investment.

How to Choose the Right Plastic Basin Injection Molding Machine
Selecting the right plastic basin injection molding machine requires careful evaluation of several key factors. Here is a practical guide to help you decide.
Consider Your Basin Size and Weight
The size and weight of your basin products directly decide the clamping force and shot capacity you need.
- Small to medium basins (diameter under 400 mm): 200–400 tons may work.
- Large basins (diameter 400–600 mm or larger): you need 500 tons or more.
The HCK530’s 530‑ton clamping force and maximum 2518 g shot weight handle large‑diameter, thick‑wall basins easily. We customize configurations and mold recommendations based on your specific product requirements.
Match Clamping Force to Mold Projected Area
A good rule of thumb: each square centimeter of projected mold area needs about 3–5 tons of clamping force. Add a 15–20% safety margin for material variations and process fluctuations.
For example, a basin mold with a projected area of 1500 cm² needs about:
- 1500 × 3.5 = 525 tons (theoretical)
- 525 × 1.15 = 604 tons (with safety margin)
The HCK530’s 530‑ton rating fits comfortably in this range for most large basin applications.
Evaluate Energy Consumption and Long‑Term Costs
Basin production runs continuously. Energy costs are a major part of your total production cost. A servo‑driven plastic basin injection molding machine saves 30–50% on electricity compared to traditional hydraulic machines.
When comparing quotes, look beyond the initial purchase price. Calculate the total cost of ownership over 5–10 years, including energy, maintenance, and spare parts.
Plan for Automation and Future Production Scaling
Modern plastic basin injection molding machines should support automation integration. The HCK530 accommodates robot interfaces for automatic part removal, sprue cutting, and stacking. This reduces labor costs and improves production consistency.
When planning your production line, consider:
- Current output requirements – daily or monthly production targets
- Future expansion – can the machine handle increased capacity?
- Auxiliary equipment – dryers, chillers, loaders, and mold temperature controllers
