Boca Raton, FL 33431, United States, 13th Nov 2026 – Yijin Solution, an experienced precision manufacturer, has announced custom fastener manufacturing as part of its service range. The offer sits alongside the company’s CNC machining work. According to the company, orders carry no minimum quantity.

Yijin Solution makes bolts, nuts and other threaded parts to customer drawings at a 12,000-square-meter facility in Shenzhen. Automotive, aerospace, medical, new energy, semiconductor and robotics are among the industries the company serves with fasteners, along with mold making and defense.

What Is New: Two Routes to a Finished Fastener

Fasteners are made by cold heading and by CNC and Swiss-type turning, the company said. Cold heading forms metal into shape in several stages without cutting material away. It suits large runs of small, uniform parts. Yijin Solution operates 150 cold heading machines. Runs can range from 10,000 to more than 1,000,000 pieces.

CNC turning and Swiss-type machining cut parts from bar stock. They suit smaller runs and parts with more complex shapes. The company runs more than 110 Swiss-type lathes, with precision tolerances starting at ±0.02 mm. For buyers choosing between routes, the split follows run size and part shape. Volume work goes to cold heading, and precision or complex parts go to turning.

“Fastener buyers often need one process for volume and another for precision,” said Gavin Yi, CEO of Yijin Solution. “Sourcing both from Yijin Solution keeps specifications in one place. Offering fasteners alongside the company’s CNC range follows that logic.”

Threads are formed by rolling or by tapping. Thread rolling is offered across a wide range of metric sizes, and tapped holes are checked with go/no-go gauges. The company also describes custom thread forms such as ACME and buttress as available through CNC turning.

Materials, Treatment and Finishes

Yijin Solution works with carbon and alloy steel, stainless steel, brass, aluminum, titanium and nickel alloys. Materials come with mill certification and batch or heat lot traceability, according to the company. Strength grades follow both SAE and ISO systems.

Heat treatment is carried out in-house, covering quenching, tempering, carburizing and induction hardening, and hardness is tested for each batch. Finishing options include zinc plating, hot-dip galvanizing, black oxide and zinc flake coatings, with passivation for stainless steel. Salt spray test reports are supplied with orders where applicable, and plating and passivation work is listed against recognized ASTM, ISO and AMS standards.

Inspection, Lead Times and Ordering

Batch checks on the fastener line use thread gauges, hardness testers, optical comparators and tensile testers. Dimensional inspection reports, material certificates and plating test results can accompany an order. The company said it holds 137 inspection instruments across its operations.

Lead times run from 7 to 15 days for samples and from 10 to 20 days for production runs. Expedited shipping is available for time-sensitive orders.

Prototype runs can be as small as 10 pieces, which suits buyers who want to start with a small batch.

Customers upload drawings through an online quoting platform, and the company states that a quote is returned within 24 hours. Fastener work is easier to review when a drawing states the thread class, strength grade, material and finish together. Yijin Solution has published fastener guides for buyers comparing suppliers in China.

Looking Ahead

Yijin Solution expects fastener requests to arrive in different materials, grades and quantities. It plans to match each one to a cold heading or turning route before production starts. Reviewing each drawing first is how the company intends to handle that range of requests.

“Each fastener drawing will continue to be reviewed for its material, thread and finish before a process is chosen,” said Yi. “The aim is to keep the quoting and inspection steps the same as order sizes change, from a prototype run to a large production order.”

Yijin Solution Rounds Out CNC Lineup With Custom Fastener Manufacturing

Boca Raton, FL 33431, United States, 13th Nov 2026 – Yijin Solution, a leading multi-process manufacturer, has announced a new 3D printing service for prototypes and production parts. The service covers plastic and metal parts, from a single concept model to repeat batches. According to the company, files are quoted online, then printed, finished and inspected before they ship.

Yijin Solution already supplies CNC machined parts, along with sheet metal fabrication, die casting and injection molding. The new service adds additive manufacturing to that range. The company said buyers can now source printed and machined parts from the same supplier.

What Is New: Five Printing Technologies Under One Order

Yijin Solution’s 3D printing service brings together FDM, SLA, SLS, MJF and metal printing under a single order, with more than 50 materials in stock, according to the company. The service supports process selection based on each part’s geometry, strength requirements and desired surface finish.

The company outlined typical applications across the five technologies. SLA is used for appearance models, clear parts and master patterns, while SLS and MJF nylon printing support housings, snap-fit components and functional parts. FDM serves applications such as jigs, fixtures and concept models, and metal printing is used for mold inserts, brackets and hydraulic components.

“Buyers who need a prototype should not have to learn several processes before they order,” said Gavin Yi, CEO of Yijin Solution. “Offering the main technologies under one order lets each part go to the process that suits it. The service provides a new production option alongside the company’s existing manufacturing services.”

Available materials include nylon, photopolymer resins and engineering thermoplastics, as well as aluminum, titanium and stainless steel. The company said resin parts can be painted in any color.

SLA uses a UV laser to cure liquid resin, while SLS and MJF fuse nylon powder layer by layer. SLS does not require separate support structures, which can simplify finishing for parts with complex geometries.

What It Means for Buyers: Finishing and Inspection in One Place

Yijin Solution says finishing is handled under the same roof as printing. Options include sanding, spray coating, color matching to RAL or Pantone references, threaded brass inserts and assembly. Buyers who want a part ready for use can therefore receive it finished rather than raw from the printer.

Inspection follows the same route. The company states that calibrated printers, 3D scanning and coordinate measuring machine checks are used to verify batches. Dimensional inspection reports, material certificates and first article inspection can accompany an order.

The service is aimed at consumer electronics, industrial equipment and agriculture, as well as product design teams and startups.

How Ordering Works

Customers upload a 3D file and receive an instant automated quote, according to the company. Complex parts and larger batches then go to an engineering review before a final quote is issued. A free printability check looks at part orientation, supports, technology and material choice, so that issues are raised before printing starts.

Once an order is placed, parts are printed, post-processed and inspected, then shipped with their reports. Express air freight is available for urgent orders. Oversized parts can be printed in sections and bonded together, the company said, which extends the service beyond the size of a single build.

Printed prototypes can also lead into volume production. Yijin Solution offers injection molding and die casting for parts that outgrow printing, and tooling comes into play only when a project moves to those processes. Keeping both stages with one supplier means the design data stays in a single place as quantities rise.

Looking Ahead

Yijin Solution expects printing requests to range from single concept models to repeat batches in nylon, resin and metal. It plans to keep 3D printing connected to its CNC machining, sheet metal and molding work, so that a part can change process as a project grows.

“Customers will keep arriving with very different parts, so each file will be checked for printability before any technology or material is chosen,” said Yi. “That early review is meant to make sure the first part printed is a useful one.”
