Service

Injection Tooling

ARTISAN specializes in mold design, manufacturing, and injection molding—combining decades of expertise with agile client collaboration. Prompt, precise communication underpins our delivery of complex precision molds, trusted by leading brands.

We leverage bi-weekly technical workshops, state-of-the-art CAM/CNC tools, and top-tier global steel/components (LKM, HASCO, DME, Meusburger) to craft durable, low-maintenance molds for mass production. Our capabilities span hot runner systems, full-range injection molding (small to large parts), two-shot/gas-assisted/multi-cavity processes, and all plastic types.

Complemented by feasibility studies and Moldflow simulations, we cut costs and ensure stable, high-quality production. That’s the ARTISAN advantage: turning ideas into high-performance molds that drive your business.

Tooling Design & Moldflow Analysis

High-quality mold design relies on hands-on experience and smooth communication—swift, accurate responses with actionable insights. We specialize in complex molds, turning project lessons into core expertise. Partnering with top clients has elevated our technical skills and service standards.

At ARTISAN, we work closely with clients to confirm key specs: mold steel, gate details, runner design, and complex two-stage ejection (e.g., multi-slides, angled lifters). We refine cooling, ejection and side-action details, and promptly flag production risks with practical advice.

Design for Manufacturing : We provide DFM(Design for Manufacturing) and Moldflow Analysis Reports. Moldflow uses advanced simulation to replicate injection molding, visualizing molten material behavior pre-production. Reports detail cooling efficiency, fill time, temperature, air traps, and more. Beyond issue-spotting, we use Moldflow to refine designs for smooth operation, lower maintenance, and a wider molding window for flawless parts.

Melt Filling Balance Technology: For multi-cavity molds, our exclusive runner flipping technology optimizes melt flow via a tumbling effect. It balances shear heat, ensuring uniform melt distribution to each cavity for simultaneous, consistent filling.

Conformal cooling : 3D-printed conformal cooling channels—shaped to mold contours—solve issues for complex parts (e.g., hard-to-reach thin sections). They enable uniform temperature control, reducing defects and shortening molding cycles.

Manufacturing

"A good mold manufacturing relies on qualified craftsmen and contemporary facilities" Artisan mould enhances the capability of project engineers and heads of mold makers by bi-weekly "case study forum"and"technical seminar"with specific topics.With those learning,our people are agile to do the right things and ask the right questions at first time,especially for complex moulds

ARTISAN continually invests in contemporary CAM software and CNC facilities to ensure a cost-efficient and time-saving machining process

ARTISAN build all the molds to meet the highest customer standards for quality and reliability, designed to withstand high volume production with minimal maintenance.we always use mould bases and standard components such as LKM, DME, HASCO, PROGRESSIVE etc. and We always use high quality steels such as 1.2311,1.2738,1.2343 and 1.2344 from Saarstahl of Germany,718, 738, S136 and 8407 from ASSAB of Sweden, P20, 420 from USA and NAK80,SKD61 and SKD11 from DAIDO of Japan

Tooling Trial

Effective mold testing revolves around three core goals: precision, performance, and stability. Leveraging our hands-on plastic mold expertise, we structure the process into three focused stages to pre-empt issues and ensure production readiness:

1. Mold Structure & Function Testing: Eliminating Hidden Issues
We rigorously test key components—ejection, gating, and cooling systems. For ejection, we confirm smooth operation without jamming or part deformation. Gating checks target no overflow and uniform melt flow. Cooling system tests verify unobstructed channels and consistent temperature to prevent warpage. We cross-reference Mold Flow data with real-world performance, fine-tuning parameters through repeated trials.

2. Sample Dimensional Accuracy Verification: Matching Design Standards
Precision is non-negotiable. Using CMMs and optical projectors, we conduct full-dimensional inspections (length, hole diameter, wall thickness, tolerances) against design drawings. We also check cavity/core wear to ensure long-term dimensional stability. For the first trial batch, we provide a detailed dimensional report for customer reference.

3. Batch Stability Testing: Simulating Mass Production
We run small-batch trials (50–200 units) to mimic continuous production. We monitor for abnormal heating, loose parts, or precision loss, while tracking pass rates to confirm stable performance under high-frequency runs. This ensures the mold meets production volume and quality requirements.
Post-testing, we archive critical data (material grade, melt temperature, injection speed/pressure, clamping pressure, etc.) as a production reference, enabling quick setup for mass manufacturing. Every step is designed to address real-world production challenges—delivering a truly production-ready mold.

4.Simulation production

For the molds to be exported, we will operate them continuously for 4 hours according to the customer's parameter standards to ensure the stability and smooth operation of the molds.
