Customized Three-Axis Servo Robotic Arms: A Procurement Guide from Requirements to Delivery

For injection molding enterprises worldwide, choosing a customized 3-axis servo robotic armthat fits their production needs is crucial to improving efficiency, reducing labor costs, and achieving intelligent transformation. However, many buyers face challenges such as mismatched specifications, delayed delivery, and unclear after-sales support during the customization process. As a leading manufacturer of automated intelligent equipment, ZHIYI (Zhejiang Zhiyi Intelligent Robot Co., Ltd.) provides a one-stop customization service from demand communication to delivery and maintenance. This guide will detail the full procurement process of ZHIYI customized 3-axis servo robotic arms, helping you avoid risks and make efficient purchasing decisions.

1. Clarify Your Production Needs: The Foundation of Customization

Before starting the customization, clarifying your core production requirements is the first step to ensure The Robotic Arm matches your injection molding line. ZHIYI’s engineering team recommends focusing on the following key parameters—these details will directly determine the design direction of the customized 3-axis servo robotic arm.

1.1 Confirm Injection Molding Machine Tonnage & Matching Requirements
The tonnage of your injection molding machine is the primary factor in selecting a robotic arm. Different tonnages correspond to different load capacities and stroke ranges of the robotic arm:
For 80~320T injection molding machines: If you mainly produce small to medium-sized products (such as electronic casings, small plastic parts), ZHIYI’s WKG-1000 3-axis single-arm single-section robotic arm (with a standard load of 3~8kg) is a suitable choice, which can realize efficient product removal.

For 350~1300T injection molding machines: If you need to handle medium-sized molds or products (such as auto parts, large plastic containers), ZHIYI’s 3-axis servo robotic arm series (with a load of 15~50kg) can meet the demand, and its high-rigidity aluminum alloy structure ensures stable operation.

For 800~4000T large injection molding machines: For heavy-duty scenarios such as complex mold picking and large product transfer, ZHIYI Bull Head 3-Axis Servo Robotic Arm (maximum load 50kg) is optimized for large strokes and high load capacity, perfectly adapting to high-tonnage equipment.

1.2 Define Load Capacity & Application Scenarios
The load capacity of the robotic arm must match the weight of your product (including fixtures). At the same time, clarify the specific application scenarios to ensure the robotic arm has corresponding functional configurations:

Basic product removal: If you only need to complete simple tasks such as taking out finished products from the mold and placing them on the conveyor belt, ZHIYI’s standard 3-axis servo robotic arm (equipped with a suction cup/fixed claw fixture) can meet the needs.

In-mold insert & water gap cutting: For scenarios requiring in-mold embedding of metal parts or post-mold water gap cutting, ZHIYI can customize a pneumatic auxiliary arm or add a servo cutting module to the robotic arm to realize integrated operations.

High-speed thin-wall product production: If you produce thin-wall products such as milk tea cups and lunch boxes (requiring fast cycle times), ZHIYI’s high-speed 3-axis servo robotic arm (empty cycle time as low as 3.5 seconds) can improve production efficiency by more than 20%.

1.3 Provide Workshop Layout & Space Constraints
To avoid installation interference, you need to provide ZHIYI with the workshop layout diagram, including:

The height of the workshop (determines the stroke of the robotic arm’s Z-axis, i.e., lifting direction).
The distance between the injection molding machine and surrounding equipment (ensures the robotic arm’s X-axis (lateral movement) and Y-axis (front-back movement) have sufficient space).

The height of the safety door and the position of the mold (avoids collision between the robotic arm and the mold during operation).

2. Select a Reliable Customization Supplier: Verify ZHIYI’s Core 

Advantages
Choosing a supplier with strong technical strength and rich experience is the key to the success of customization. ZHIYI has won the trust of global customers (such as HAERS, CAYI, and FEIJIAN) with its professional capabilities. When evaluating suppliers, you can focus on the following aspects:

2.1 International Quality Certification & Technical Patents
Quality is the cornerstone of customized equipment. ZHIYI’s 3-axis servo robotic arms have passed ISO9001 quality management system certification and EU CE certification, and all products undergo rigorous load testing, fatigue testing, and safety performance testing before leaving the factory to ensure compliance with international standards.
