Recently, a leading humanoid robot company officially opened its A-share subscription on the Science and Technology Innovation Board, marking the beginning of the robot industry's transition from concept demonstrations to mass production verification. The manufacturing processes and supply chain capabilities that support its mass production are also receiving increasing attention. For the injection molding industry, structural parts, appearance parts, transmission parts
sensorCore components such as brackets and battery casings are opening up a new incremental market.
Compared to 3D printing and CNC machining,The injection molding process has significant advantages in efficient batch forming and comprehensive cost control, and has become a key path for robot mass production.
Faced with this trend,Zhenxiong has already laid out injection molding solutions covering all scenariosWhether it is high-precision micro components, high rigidity structural components, or multi material composite components, mature process guarantees can be provided.
Small precision parts
Miniature Precision Parts
Typical products: Micro gears, sensors
Common materials:
POMThe
PEEK、PC、LCP、COC
Required locking force: 50-150t
Production difficulties:
Small size fine structure forming
Dimensional consistency
Product appearance control
Micron level accuracy is the lifeline of small precision components. The sensor bracket and micro transmission gear need to maintain extremely high operational stability in a very small space. Any slight deformation or burrs on the appearance may cause signal distortion or jamming. The strict appearance standards also impose almost stringent requirements on the repeated positioning accuracy and temperature control stability of injection molding equipment during the production process.

Medium sized structural components
Medium-sized Structural Component
Typical products: Joint brackets, connectors
Common materials: PBT, PA, fiberglass reinforced PA

Production difficulties:
Lightweight
structural strength
Dimensional stability under long-term action
The balance between high strength and lightweight is the core challenge for medium-sized structural components. As the force core, the joint bracket not only needs to withstand the impact under dynamic loads, but also avoid warping deformation caused by internal stress. How to balance dimensional stability and mechanical performance during high-speed injection molding is the key to mass production and implementation.

Dimensional accuracy control
Large appearance components such as the chest cavity, shell, and mask not only provide protection and structural coverage, but also directly affect the overall texture of the robot. During the mass production process, it is important to focus on surface quality, dimensional stability, and assembly compatibility to minimize the impact of shrinkage, weld lines, warping, and other issues on appearance and assembly.

Required locking force: 358-1500t
Production difficulties:
Multi material interface combination
Positioning accuracy of embedded components
In humanoid robots, many components require composite materials to simultaneously meet structural support, tactile sensation, protection, connection, or assembly requirements. Biomimetic fingers and flexible encapsulated components may involve the combination of silicone or soft elastomers with plastics; Partial connectors, supports, or integrated shells may also involve composite molding of metal inserts and engineering plastics.
In the production of such components, it is not only necessary to "make different materials together", but also to pay attention to the stability of the bonding between materials, the positional accuracy of metal inserts, the deformation risk caused by the shrinkage differences of different materials, and the reliability in long-term use.

The challenge of mass production and implementation of humanoid robots still lies in the material aspect. Materials represented by PEEK and LCPNot only is the price expensive, but it also has almost stringent requirements for production processesThe traditional "master technician adjusts machines based on experience" model often means long trial molding cycles and staggering waste costs.
In order to solve the dilemma of "expensive materials are difficult to adjust", Zhenxiong has simultaneously launched a solution outside the equipment matrixiChen ™ AI Molder is a great helper for intelligent injection molding.
iChen™AI Molder
Intelligent mold adjustment drives precise mass production
Product Highlights:
Intelligent parameter tuning
Stable production
Zhenxiong is an intelligent injection molding tool created by integrating advanced industry models. After loading, the operator only needs to input the basic product information and material name to quickly generate scientific process parameters. For common defects such as material shortage and flash, it is more effectiveOne click generation of correction strategy, significantly reducing the trial molding cycle.
In the mass production stage, AI Molder can automatically and dynamically compensate for process curves by monitoring key process data such as injection and holding pressure in real time, effectively offsetting interference such as fluctuations in raw material batches and changes in environmental temperature and humidity,Ensure long-term stable delivery quality and help factories quickly overcome the ramp up period of "trial production mass production".

The competition in the robotics field is a battle between algorithms in the first half, and inevitably a battle between supply chain and cost in the second half. With the further decrease in the cost of humanoid robots and the increase in production demand, Zhenxiong will continue to provide stable, efficient, and scalable injection molding equipment solutions support for customers in the robot industry chain, focusing on precision parts, structural parts, appearance parts, and multi material composite parts.
Under the trend of humanoid robots, where are the opportunities in the injection molding industry?
