Based locally, serving the world
Haijin specializes in stainless steel silica sol precision casting, post-casting machining, and CNC machining of non-standard parts. From drawing evaluation, material selection, mold making and casting, to critical dimension machining and inspection delivery, we reduce the costs of multi-supplier collaboration.
For mechanical equipment, water pumps and valves, building hardware and non-standard metal parts, evaluate the process according to the requirements of structure, material, precision, quantity and surface treatment.
Suitable for complex three-dimensional structures, stainless steel and alloy steel parts, taking into account surface quality, dimensional stability and batch consistency.
Understanding Precision Casting
We offer turning, milling, drilling, tapping, and machining of mating surfaces and critical dimensions, suitable for post-machining of castings and custom manufacturing based on provided drawings.
Check processing capacity
It covers door control, bathroom and building metal parts, and supports structural optimization, pre-processing before surface treatment and batch delivery.

From wax molding, shell making, and melting to sandblasting, shaping, machining, and inspection, we put the key links that affect assembly and lifespan in the same quality chain.
First, assess the structure, materials, precision, and quantity, and then determine the casting, machining, inspection, and delivery plan.
Receive 2D drawings, 3D models, samples, and quantity information.
Analyze the structure, materials, machining allowances, and quality risks.
Determine the mold design and complete the first piece and dimensional verification.
Waxing, shell making, melting, casting and post-treatment.
Complete the holes, threads, mating surfaces, and critical dimensions.
Inspect, package, and arrange bulk shipments as required.
Material selection, process differences, tolerances, and surface treatment not only affect the price, but also the lifespan of parts, assembly risks, and the total project cost.
Submit your material, quantity, size requirements, and drawings. We will assess a more suitable production path based on casting, machining, and inspection requirements.
