Key takeaways:

  • Jinchen’s 2 laminator models mainly differ in lamination area, which directly impacts module throughput per cycle

  • Both systems support large module formats and multi-stack configurations, enabling multiple modules to be processed simultaneously

  • Lamination is carried out through multi-stage heating and cooling, with cycle times of about 8-10 minutes depending on the process recipe

Jinchen, one of the leading laminator suppliers, lists 2 products in the Taiyangnews Market Survey on Solar Module Production Equipment 2026. The company began as a laminator supplier and eventually built expertise in other fields, quickly becoming a one-stop solution provider for module production equipment. For the survey, the company has provided details on 2 products – 2787 and 27115 – that are commercially available since 2020 and 2022, respectively. The key difference between the 2 models is the total lamination area, and therefore, the throughput – the latter, which is the latest, has a higher throughput.

Both are large-area laminators with a total usable lamination area of 2,700 × 8,700 mm for the 2787 model and 2,700 × 11,500 mm for the 27115 model. Both have an optional double-layer or double-stack openings for module inputs.

Each of these models can accommodate a maximum panel size of 2,520 × 1,450 mm. With 182 mm cell-based modules and utilizing both openings of the machine, 2787 can accommodate 14 modules, whereas the 27115 can accommodate 18 modules. Loading is supported by a conveyor belt or a stacked loading, while unloading is supported by a roller conveyor system, in addition to the conveyor belt and stacked unloading. Both machines support a laminate thickness of up to 10 mm and a load of about 50 kg. These machines use oil or electric heating with a minimum heating rate of 1.44°C/ min, and take up to 90 minutes to heat from 20°C to 150°C. The company also offers double-sided heating as an optional feature. They have 2 heating zones. The spec for the temperature uniformity of the metal plates in both cases is an allowed deviation of ±1.5°C. For cooling, both models use either air or water-cooling systems. Both models have a pin-lifting system available on request. An external vacuum system supports the lamination process. The 2787 model measures 47,800 × 4,970 × 3,480 mm and weighs 164 tons, whereas the 27115 model measures 61,370 × 4,970 × 3,480 mm and weighs 214 tons. The longer length of 27115 enables it to accommodate 4 additional modules than 2787.

On the process side, these machines support all kinds of encapsulants, such as EVA, TPO, POE, etc. In addition to glass-glass configuration, they also support glass-backsheet designs. For both of these large-area laminators, the process accommodates 1 or 2 stacks in either a double- or a triple-chamber. The 3-stage process, including evacuation, curing, and cooling, may happen in a 2-chamber or 3-chamber variant. In the dual-chamber variant, evacuation, pre-heating, and curing occur in chamber 1, while cooling occurs in chamber 2. The laminator supports a lamination temperature up to 180°C and pressure as low as -100 kPa. The time from evacuation till cooling is between 8 and 10 minutes for an EVA + POE lamination stack. This implies that the 2787 model can produce 76 modules/h in a 144 half-cell configuration, and 27115 can produce 98 modules/h in the same configuration. Although the gel content of the cured material depends on the encapsulant and the lamination process recipe, Jinchen shared that the degree of cross-linkage for the cured laminate is between 75% and 85%. The mechanical yield and the system uptime for both models are at least 99.9% and 99.5%, respectively. Since both models are large-area laminators, there is no changeover time required to laminate a module of a different size. However, it requires about 10 minutes to change a single silicone membrane after 12,000 cycles of operation.
