Why Choose Our Die Casting Service
Custom die casting projects often require more than a casting supplier. They require early manufacturability input, stable tooling, reliable post-processing, consistent inspection, and responsive project communication. Honjenny is structured to support these needs from the first RFQ to repeated production orders.
Prototype to Mass Production Support
From rapid prototypes and sample validation to tooling, pilot runs, and 50,000+ piece production, Honjenny supports customers through each stage of product development and manufacturing scale up.
Engineering Oriented Support
Our team reviews part geometry, draft angles, wall thickness, gates, ejector positions, machining allowances, and finishing requirements to help reduce porosity, improve filling stability, and support long-term production quality.
Aluminum and Zinc Alloy Expertise
We support both aluminum HPDC and zinc hot-chamber die casting, allowing customers to choose the right alloy and process based on strength, weight, complexity, surface quality, cost, and production volume.
Precision Secondary Machining
For dimensions that cannot be achieved by die casting alone, we provide CNC machining for key functional features. Turning tolerance can reach up to ±0.005 mm and milling tolerance can reach up to ±0.01 mm depending on geometry, material, feature type, and inspection requirements.
Quality Controlled Production
Our inspection capabilities include CMM, 2D measurement, X-ray inspection, hardness testing, salt spray testing, FAI, and material certification support for demanding automotive, electronics, communication, and industrial applications.

Read more12 Different Types of Metal Casting for Precision Manufacturing
Choosing a casting process affects more than the initial tooling price. It also influences filling quality, dimensional stability, machining time, surface finish, production yield, and final part cost. This guide explains the main metal casting methods used from prototype development to high-volume production. It compares each process by material, geometry,...
Read moreTitanium vs Steel: Which Metal Is Right for Your Project?
The titanium vs steel comparison cannot be reduced to deciding which metal is stronger. Titanium is lighter and highly corrosion-resistant, while steel is usually stiffer, easier to process, and more economical. In Honjenny projects, customers sometimes specify either material when aluminum can meet the actual requirements. This guide explains how...
Read moreVacuum Die Casting: Process, Benefits, and When to Use It
Vacuum die casting is used when conventional high-pressure die casting cannot provide stable internal quality for sealed, thin-walled, welded, or heat-treated parts. The process removes air from the die cavity before and during metal injection, reducing the gas available to form pores. In one Honjenny ADC12 housing project, this change...
Frequently Asked Questions
What files do you need to quote a custom die casting part?
Please send 2D drawings, 3D CAD files, material requirements, surface finish requirements, tolerance notes, estimated order quantity, and any inspection standards. If drawings are not complete, our team can review the available files first and confirm missing details.
Can you review my design before mold making?
Yes. Honjenny can review wall thickness, draft angles, ribs, bosses, holes, parting lines, gate positions, machining allowances, and surface finish requirements before mold manufacturing.
What affects the cost of a die casting project?
The main cost factors include part size, alloy, mold structure, cavity number, tolerance requirements, CNC machining time, surface finish, inspection requirements, and annual production volume.
How do you handle tight tolerance features on die cast parts?
Features that require tighter tolerances are usually finished by CNC machining after casting. These may include sealing surfaces, threaded holes, positioning holes, flat mating faces, bearing seats, and assembly interfaces.
Can you provide inspection reports with the parts?
Yes. Depending on the project, Honjenny can provide dimensional inspection reports, FAI reports, material certification, salt spray test reports, X-ray inspection results, and surface finish inspection records.
Do you work with overseas customers?
Yes. Honjenny serves customers in North America and Europe. We can communicate by drawings, CAD files, samples, inspection requirements, and project specifications for custom aluminum and zinc die casting projects.
