This detailed case study demonstrates how Suzhou Lizhu Machinery Co., Ltd. delivered comprehensive production upgrades for a well-known Indian manufacturer, leveraging our flagship standard vertical injection molding machine and upgraded vertical insert molding machine to resolve long-standing production bottlenecks, elevate finished product yield and cut overall operational expenditure. As a professional manufacturer specializing in plastic injection molding equipment, Lizhu Machinery has established long-term and mutually beneficial partnerships with processing enterprises across Southeast Asia, South Asia, South America and other emerging markets. This successful project fully verifies the outstanding performance, structural rationality and wide applicability of our full range of vertical injection molding machine and vertical molding machine in high-precision insert molding industries 

The cooperating client is a reputable manufacturing enterprise headquartered in New Delhi, India, focusing on R&D and mass production of electronic terminals, wiring harness assemblies and micro precision plastic connectors. Driven by surging overseas order volumes in recent months, the company’s aging traditional injection molding equipment could no longer meet modern production standards. The old units suffered from unstable mold clamping force and poor positioning accuracy for metal embedded parts, which frequently caused manufacturing defects such as material flash and inconsistent composite bonding. The high defective rate led to severe raw material loss and increased production costs. Moreover, the bulky old machines occupied excessive plant area and featured high power consumption. After in-depth screening and comparison among numerous equipment suppliers via global search engines and mainstream B2B platforms, the client finally chose Lizhu Machinery and placed a bulk order of standard vertical injection molding machine and vertical insert molding machine to implement full workshop renovation.

Our professional technical team from Suzhou Lizhu Machinery designed a customized turnkey solution based on the client’s product specifications, molding processes and on-site workshop conditions. We selected the mature standard vertical injection molding machine as the core production unit. Adopting industry-proven vertical clamping and vertical injection structure, this vertical injection molding machine features an open working platform, enabling operators to complete metal insert placement efficiently and accurately. Its high-rigidity one-piece frame structure guarantees stable mechanical performance during round-the-clock continuous production. Meanwhile, we configured multiple sets of optimized vertical insert molding machine to undertake core insert overmolding procedures. Equipped with a precision digital control system, this equipment supports stepless adjustment of injection pressure and injection speed, fully complying with the stringent quality criteria for electronic components. All models of our vertical molding machine adopt space-saving compact layout, which effectively optimizes the utilization rate of the client’s limited workshop space.

Upon equipment arrival, senior engineers from Lizhu Machinery finished on-site installation, mechanical commissioning and professional operator skill training within three working days. The client officially put the newly delivered standard vertical injection molding machine and vertical insert molding machine into formal operation. After one month of stable trial production, all production indicators achieved remarkable improvement. The defective rate of plastic-metal composite components dropped from 18% to less than 3%. The intelligent control module of the vertical injection molding machine minimized manual intervention, shortened single molding cycle and lifted daily production capacity by nearly 26%. Benefiting from the energy-saving hydraulic drive system, the power consumption of the entire production line was effectively reduced. The stable mechanical operation of our vertical molding machine also greatly reduced daily equipment maintenance workload and labor input.

The client’s production management team spoke highly of the products and after-sales services provided by Suzhou Lizhu Machinery. They commented that the standard vertical injection molding machine and vertical insert molding machine from Lizhu are user-friendly, operationally stable and cost-efficient. The equipment completely solved their persistent problems in product quality and production efficiency, and greatly strengthened their core market competitiveness. To expand production scale, the client has placed a repeat order for additional vertical injection molding machine units.

Up to now, Lizhu Machinery’s vertical injection molding machine, standard vertical injection molding machine and vertical insert molding machine have served hundreds of manufacturing clients around the globe. Beyond supplying high-quality vertical molding machine equipment, we also provide one-stop industrial services including process solution customization, technical training and full-life-cycle equipment maintenance.
