Our Company Breaks Through the Core Technology of Super-Large Logistics "Chuan" Pallet Gas-Assisted Injection Molds, Helping Global Smart Warehousing Reduce Costs and Increase Efficiency!

— China's First Super-Large "Chuan" Pallet Gas-Assisted Mold Successfully Delivered, Cutting Molding Cycle by 22% and Boosting Load-Bearing Strength by 40%

Recently, our company has achieved a major technological breakthrough in the field of large-scale logistics equipment manufacturing. After six months of intensive research, our technical team successfully overcame two major industry challenges — thick-wall shrinkage and gas-channel balance — and officially delivered China's first super-large "Chuan" pallet gas-assisted injection mold. The implementation of this mold marks a new stage in China's gas-assisted molding of super-large logistics pallets, providing a more competitive solution for the global smart warehousing industry's demand for high-strength turnover and lightweight design.

Industry Pain Points: Super-Large Pallet Molding Is Difficult; Traditional Processes Hit a Bottleneck

With the rapid development of global smart warehousing and logistics automation, "Chuan" pallets — as core carriers for rack storage, forklift turnover, and AGV handling — are seeing continuously rising market demand. Especially in e-commerce logistics, cold-chain warehousing, and intelligent manufacturing, super-large, high-load-bearing, and lightweight plastic pallets have become a rigid necessity.

However, the injection molding of super-large "Chuan" pallets has long faced two major technical bottlenecks:

• Thick-wall shrinkage challenge: The significant wall-thickness difference between the pallet's reinforcing ribs and the main body makes traditional injection molding highly prone to voids and sinks, affecting load-bearing strength and appearance quality;
• Gas-channel balance challenge: In gas-assisted injection, uneven nitrogen pressure distribution within ultra-long runners leads to unbalanced filling and insufficient gas penetration, making yield rates difficult to guarantee.

Previously, domestic super-large "Chuan" pallet gas-assisted molds mostly relied on imports, involving high costs and long lead times, becoming a "bottleneck" restricting cost reduction and efficiency improvement in smart warehousing.

Technical Breakthrough: Six Months of Research, Two Core Challenges Overcome One by One

Facing industry challenges, our company's technical team established a dedicated task force in early 2024, carrying out full-chain independent innovation from mold-flow analysis, gas-channel design, and cooling systems to process parameters.

Overcoming thick-wall shrinkage: Through high-precision mold-flow simulation and orthogonal experiments, the team optimized gate positions and runner layouts, and innovatively adopted a "zoned gradient packing + conformal cooling" solution, reducing the shrinkage rate in thick-wall areas to within 0.3% and completely eliminating voids and sink marks.

Solving gas-channel balance: Targeting the pressure decay problem in ultra-long gas channels, the team independently developed a "multi-stage splitting + dynamic balancing valve" gas-assisted control system, achieving a pressure deviation of less than 2% across 12 parallel gas channels, ensuring precise gas penetration and uniform filling, and greatly improving yield and consistency.

Remarkable Results: Cycle Cut by 22%, Load-Bearing Strength Up by 40%

Verified through actual testing, this super-large "Chuan" pallet gas-assisted mold delivers outstanding results:

• Molding cycle shortened by 22%: By optimizing cooling water channels and the gas-assisted demolding sequence, single-piece molding time dropped from 180 seconds under traditional processes to 140 seconds, significantly increasing capacity;
• Load-bearing strength increased by 40%: The gas-assisted hollow structure greatly enhances the pallet's flexural strength and impact resistance, with dynamic load capacity exceeding 2.5 tons and static load reaching 8 tons, fully meeting the high-strength turnover needs of smart warehousing;
• Further lightweighting: While increasing load capacity, product weight is reduced by 25% compared with solid pallets of the same specification, effectively lowering logistics transportation energy consumption and AGV loads.

Customer Value: Reducing Costs and Increasing Efficiency, Empowering Global Smart Warehousing

The mold has been successfully applied by a leading domestic logistics equipment enterprise, and the first batch of super-large "Chuan" pallet products has rolled off the line and been delivered for use. Customer feedback shows:

• Comprehensive manufacturing cost per piece reduced by 18%;
• Product qualification rate raised from 92% to 98.5%;
• Mold life expected to exceed 500,000 cycles, with significantly lower maintenance costs.

"The delivery of this gas-assisted mold not only breaks the foreign technology monopoly, but also gives us rapid response and cost advantages in the super-large pallet market," said the customer's project manager.

Looking Ahead: Continuous Innovation to Lead the Intelligent Upgrade of Logistics Equipment Manufacturing

The successful delivery of this super-large "Chuan" pallet gas-assisted injection mold is a concentrated demonstration of our company's technical strength in the field of large precision molds. In the future, we will continue to deepen our work in gas-assisted injection, microcellular foaming, lightweight composite materials, and other cutting-edge processes, working hand in hand with global partners to drive smart warehousing and logistics equipment toward a more efficient, greener, and more intelligent future.

Cost reduction and efficiency improvement start with the mold. Our company is ready to join hands with peers in the global smart warehousing industry to create a new future of lightweight logistics!
