Frequently Asked Questions (Quick Answers)

Q1: Can King Square customize sampling needles according to CAD drawings? ▼

Yes. King Square specializes in OEM/ODM custom sampling needles. We support custom bevel tip angles (12°, 17°, 30°, 45°), side hole drilling, multi-lumen coaxial structures, and surface coatings (Teflon, Titanium Nitride, or Super-lubricating hydrophilic coating).

Q2: What is the delivery lead time for standard products and custom modules? ▼

Standard catalog components (miniature guide rails, standard plunger pumps, electric grippers) are usually in safety stock and ship within 3-5 working days. Custom modules and OEM needle prototypes typically require 2-3 weeks.

Q3: What communication buses do King Square smart electric grippers and motors support? ▼

Our integrated electric grippers and stepper motors support standard digital IO, Modbus RTU (RS485), and CANopen buses, making them easily compatible with mainstream PLCs, upper computers, and motion controllers.

Q4: Are King Square components compliant with ISO9001 and medical quality standards? ▼

Yes. King Square operates strictly under ISO9001:2015 quality management systems. Every product batch undergoes rigorous dimensional, sealing, and endurance tests before shipment.
