Changzhou Hongxinyutai Precision Mold Co., Ltd. proudly presents our OEM Thick-Wall PMMA Cosmetic Jar Injection Mold — a precision-engineered tooling solution designed for high-volume production of thick-walled PMMA jars. With 1×4 cavities, premium S136 stainless steel construction, and full robotic arm readiness, this mold delivers consistent quality, extended tool life, and seamless automation integration. Backed by our ISO/TS16969-certified facility and over 7 years of mold manufacturing expertise, we ensure your cosmetic packaging meets the highest standards of clarity, durability, and surface finish.

Key Features & Technical Specifications

1×4 Cavity Layout: Optimized for balanced filling, reduced cycle time, and consistent part quality across all cavities.
S136 Mold Steel: High-grade stainless steel with excellent corrosion resistance, wear resistance, and polishability — ideal for transparent PMMA products.
Thick-Wall Design Support: Engineered to handle thick-walled (≥3mm) PMMA parts, minimizing sink marks and internal stress.
Robotic Arm Ready: Standardized ejector plate layout, gripper grooves, and mounting holes for quick integration with 3-axis or 6-axis robots.
Hot Runner / Cold Runner Options: Customizable runner system to suit your production requirements (hot runner for high-speed, cold runner for cost efficiency).
Precision Cooling System: Conformal cooling channels ensure uniform mold temperature, reducing cycle time by up to 20%.
Surface Finish: SPI A1 / Mirror polish achievable on cavity, delivering high-gloss PMMA jars without secondary polishing.
TS16969 Quality Management: Each mold undergoes rigorous inspection (CMM, hardness test, trial injection) before shipment.

Parameter	Specification
Mold Base	Standard LKM / DME (customizable)
Cavity / Core Steel	S136 (HRC 48-52)
Number of Cavities	1×4
Product Material	PMMA (Acrylic)
Wall Thickness Capacity	2 – 8 mm
Cycle Time Estimate	15 – 25 seconds (depending on part design)
Robotic Interface	Standard gripper grooves + mounting pattern
Mold Life Expectancy	500,000 – 1,000,000 shots (with proper maintenance)

Customer Benefits

High Clarity & Aesthetics: Mirror-finished S136 cavities produce PMMA jars with exceptional transparency, free from flow marks or bubbles.
Reduced Downtime: S136’s corrosion resistance prevents rusting when processing hygroscopic PMMA, extending maintenance intervals.
Automation Ready: Pre-designed robotic interface allows immediate integration with your existing injection molding cell, reducing labor costs.
Cost-Effective Production: 1×4 cavity layout doubles output compared to single-cavity molds, lowering per-part cost for medium-to-high volumes.
Consistent Quality: Balanced runner system and precise cooling deliver uniform part dimensions and minimal warpage.
Customization Flexibility: Options for different gate types, ejection method, and surface texture (matte, gloss, or frosted) are available.

We will provide a competitive quote and free DFM (Design for Manufacturing) analysis to optimize your part design before tooling begins.

Frequently Asked Questions (FAQ)

Q: What is the typical lead time for this mold?
A: Standard lead time is 25–35 working days from design approval, including trial shots and final inspection. Rush orders can be arranged upon request.
Q: Can the mold be adapted for other materials like PP or PETG?
A: While optimized for PMMA, the mold can be reworked for other materials with minor modifications (e.g., gate size and cooling layout). Please discuss your material with our engineers.
Q: Does the mold include a hot runner system?
A: The mold is designed to accommodate either hot runner or cold runner. The standard configuration is cold runner. Hot runner upgrade is available at additional cost.
Q: How do you ensure the mold works with my robotic arm?
A: We provide a standard robotic interface drawing (gripper groove dimensions, mounting hole pattern) that suits most brands (ABB, Fanuc, Kuka, etc.). Custom patterns are possible with your robot specification.
Q: What is the maximum jar diameter this mold can produce?
A: The mold can produce jars up to 80mm in diameter and 120mm in height, depending on the specific cavity design. We recommend sending your 3D model for feasibility check.
Q: Is the S136 steel heat-treated? What hardness?
A: Yes, S136 is vacuum heat-treated to HRC 48–52 for optimal wear resistance and toughness. A nitriding treatment is optional for even higher surface hardness.
Q: Do you provide samples before mass production?
A: Yes, after tooling completion we perform trial injection and send first-shot samples (T1 samples) for your approval. Once approved, we proceed with mold validation and shipment.
Q: What warranty do you offer?
A: We provide a 12-month warranty against manufacturing defects (excluding normal wear). Spare parts for hot runners, guides, and ejector pins are available at cost.
