JoinCast FAQ
Do you only provide die casting, or can you handle complete part finishing?
JoinCast operates as a vertically integrated manufacturer with all processes under one roof at our 9,900 m² facility. Components progress from mold engineering and die casting through CNC machining, polishing, shot blasting, surface treatment, TPR insert molding, printing, and quality inspection without leaving our facility.
This eliminates coordination across multiple suppliers and reduces your total landed cost.
What industries and applications does JoinCast specialize in?
We serve marine components requiring corrosion-resistant ADC-3 / A383 alloy, pneumatic tool housings and mechanisms, agricultural machinery components for outdoor durability, LED lighting heat sinks optimized for thermal management, and medical equipment parts requiring tight tolerances.
Our die casting machines (135T-900T) and precision CNC capabilities handle parts from 10g to 3kg+ across these demanding applications.
What certifications and quality standards does JoinCast maintain?
JoinCast is ISO 9001:2015 certified with comprehensive quality management systems covering all production processes. Our 10-member quality team uses 2 Mitutoyo CMM systems, Keyence 3D scanning, material spectrometry, salt spray testing, and surface roughness verification.
We provide complete documentation including first article inspection reports, material certifications, dimensional reports, and traceability records required for medical equipment and automotive applications.
Can your team communicate effectively in English for engineering and commercial discussions?
Our sales, engineering, and quality teams can communicate in English, Japanese and Chinese for all customer interactions including technical discussions, drawing reviews, and project coordination. We provide English-language quotations, inspection reports, and documentation.
Taiwan’s export-focused manufacturing culture means our staff has extensive experience working with North American and European customers. Video conferences can be scheduled to accommodate Western time zones.
How do you protect customer intellectual property and proprietary designs?
All customer designs, CAD files, and proprietary information are protected under non-disclosure agreements standard in our contracts. Molds and fixtures remain secured within our facility with access limited to assigned production teams.
Taiwan’s strong intellectual property legal framework and our relationships with Fortune 500 clients reflect our commitment to confidentiality. We never produce similar parts for competitors without explicit customer permission.
What's the process for getting a quote and starting a new project with JoinCast?
Submit your CAD files (STEP, IGES formats) and 2D drawings with specifications through our contact form or email. Our engineering team provides quotations within 5-7 business days including DFM feedback, recommended process flow, tooling costs, piece prices at different volumes, and estimated timelines.
After quote approval, we proceed with mold design review, simulation, fabrication, sampling, and your approval before production begins.
