Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your reliable partner in precision mold manufacturing since 2017. Our OEM Mold for Square Thick-Wall Cosmetic Jars is engineered to meet the highest standards of the cosmetic packaging industry. Featuring an advanced mold protection system and robotic arm collection design, this mold ensures superior product quality, extended tool life, and fully automated production. Whether you need a custom cavity configuration or a specific surface finish, we deliver tailored solutions to boost your production efficiency.
Square thick-wall cosmetic jars require exceptional precision and durability. Our mold is built with high-grade steel (718H/2738) and undergoes rigorous heat treatment to withstand high injection pressures and continuous cycles. The integrated mold protection mechanism monitors cavity pressure, temperature, and ejector pin movement in real time, preventing damage from stuck parts or material buildup. Paired with a robotic arm collection system, finished jars are automatically picked, oriented, and placed onto conveyor belts – reducing labor costs and minimizing scratches or contamination.
Key Features & Benefits
- Precision Square Cavity Design: Achieve consistent wall thickness and sharp corners for premium cosmetic jars.
- Smart Mold Protection: Sensors and interlocks prevent damage from flash, overpacking, or ejection failures – extending mold life by up to 30%.
- Robotic Arm Integration: Compatible with most 6-axis or SCARA robots; optional gripper design for different jar sizes.
- Fast Cycle Time: Optimized cooling channels and runner design reduce cooling time by 15% compared to conventional molds.
- Flexible Cavity Count: Standard in 4, 6, or 8 cavities; custom up to 16 cavities upon request.
- Strict Quality Control: Every mold tested with trial shots and dimension reporting per TS16969 standards.

Our molds are designed to produce square thick-wall cosmetic jars with ±0.05mm tolerance and mirror-like surface finish. The robotic arm collection system not only increases throughput but also eliminates manual handling that could cause defects. This integrated solution is especially beneficial for high-volume production lines where consistency and uptime are critical.

Frequently Asked Questions (FAQ)
Q1: Can you customize the mold to fit my existing injection molding machine?
A: Yes. We customize the mold base dimensions, clamping ring, ejector pattern, and robot interface to match your machine's specifications. Provide us with your machine model or parameters.
Q2: How does the mold protection system work exactly?
A: It uses a combination of pressure sensors inside the cavity, temperature monitors, and ejection stroke detectors. If any parameter exceeds set limits (e.g., stuck part or material flash), a signal is sent to the injection machine to stop the cycle, preventing mold damage.
Q3: What is the typical lead time for an OEM mold?
A: Usually 30–45 days from design approval to first shipment. Complex molds with hot runner and robotic integration may require 50–60 days. We will provide an accurate timeline after reviewing your design.
Q4: Can the robotic arm handle jars with different weights or shapes?
A: Yes. The gripper design can be customized with adjustable fingers or vacuum cups to accommodate various jar sizes (e.g., 15g, 30g, 50g). We will test the pick-and-place cycle before shipping.
Q5: Do you provide samples before mass production?
A: Absolutely. After mold trial, we send you samples for approval. We can also make minor adjustments to the mold based on sample feedback at no extra charge (within reason).
Q6: What is the minimum order quantity (MOQ) for such molds?
A: We accept single mold orders. There is no MOQ, but for molds with robotic arm collection, we recommend at least one set of spare parts for quick maintenance.
Q7: Is the TS16969 certification applicable to all molds you produce?
A: Yes, our entire production process follows TS16969 quality standards, including design, manufacturing, inspection, and delivery. This ensures traceability and consistent quality.
Q8: What payment terms do you accept?
A: We typically work with T/T (30% deposit, balance before shipment) or L/C at sight. Other terms negotiable for long-term partners.
