Provincial-level New Industrial Product – 144-Cavity Needle Valve Hot Runner PET Preform Precision Injection Mold

SINOMOULD “144‑Cavity PET Preform Mould” Recognised as Zhejiang Provincial New Industrial Product

On August 13, 2021, the Zhejiang Provincial Department of Economy and Information Technology organised an expert review and appraisal meeting for provincial‑level new industrial products. SINOMOULD’s self‑developed “144‑Cavity PET Preform Injection Mould” successfully passed the review and was recognised as a Zhejiang Provincial New Industrial Product – marking provincial‑level authoritative recognition of the company’s technical strength in the design and manufacturing of high‑cavity precision moulds. As the competent authority for the industrial and information technology sectors in Zhejiang Province, the “Provincial New Industrial Product” designation requires that the product demonstrates significant achievements in technical breakthroughs, process improvement, product innovation, and quality enhancement; possesses leading technological levels; has key core technologies and independent intellectual property; and that the enterprise’s average R&D investment in the previous two years is not less than 3% – with stringent evaluation standards and high recognition value.

Breaking International Monopoly – Filling a Domestic Technology Gap

144‑cavity high‑cavity injection moulds have long been monopolised by international giants such as HUSKY, SIPA, and NETSTAL, leaving domestic preform manufacturers facing high procurement costs and long delivery lead times. SINOMOULD’s successful independent development of this product marks a domestic breakthrough in key 144‑cavity mould technology, effectively driving import substitution in the critical field of injection moulds.

This product can injection‑mould 144 PET preforms in a single shot, increasing production efficiency several times over conventional moulds. Customers can obtain moulds with technology equivalent to international brands while significantly reducing mould procurement costs and substantially shortening delivery lead times – gaining significant cost and efficiency advantages in the highly competitive beverage packaging industry.

Core Technical Breakthroughs – Design Level Reaching Industry Advanced Standards

The 144‑cavity mould imposes extremely high requirements on runner system balance. SINOMOULD’s technical team used rheological theory to calculate the structural dimensions of the runners at each level, and combined with Moldflow simulation software to verify the hot runner system – ensuring that the plastic melt reaches each cavity simultaneously, achieving molding consistency across all 144 cavities. Among these, the design of the 144‑cavity valve‑gated hot runner system is recognised in the mould industry as a highly difficult technology. Its successful development demonstrates that the company has reached an industry advanced level in high‑cavity mould design.

In terms of product compatibility, this mould can seamlessly interface with high‑speed dedicated PET injection systems from international mainstream brands such as HUSKY, NETSTAL, and SIPA – meeting the rigid demand of the beverage packaging industry for ultra‑high production efficiency.

Precision Quality Control – Meeting the Stringent Standards of High‑End Packaging

Provincial New Industrial Product designation requires that the product has mature technology, reliable quality, good performance, and has been tested by a third‑party testing institution. During the injection molding process of the 144‑cavity mould, SINOMOULD precisely controls key parameters such as temperature control, pressure balance, and cooling uniformity – ensuring that the 144 preforms maintain high consistency in dimensional accuracy, wall thickness uniformity, and appearance quality – meeting the stringent quality requirements of high‑end PET packaging customers.

Validity and Ongoing Compliance

According to the management requirements of the Zhejiang Provincial Department of Economy and Information Technology, the provincial new industrial product evaluation result is valid for three years from the date of publication. Recognised enterprises must report annual economic and social benefit indicators within the validity period and accept ongoing tracking evaluation. SINOMOULD will continue to follow up on the reporting requirements, ensuring that the product’s economic and social benefit indicator data remain complete and traceable.

This recognition as a Provincial New Industrial Product is a concentrated reflection of SINOMOULD’s technological innovation capability, and further consolidates the company’s technology leadership position in the PET packaging mould segment.
