custom made stainless steel bolt drawing design and analysis

If your custom made stainless steel bolt is accompanied with the 3D or 2D drawing, the dimensions that you add on the technical drawing are the important part that will be checked by HZW factory engineers.

It is recommended to dimension all important features on your drawings though to avoid misundersatnding and errors.

Before confirmed the order with clients, our professioanl team will check all drawings and requests with customers carefully again and again. It can ensure zero production mistakes.

More information on adding dimensions to your drawing can be found in this detailed article by Massachusetts Institute of Technology.

În HZW, our priority is to provide a complete custom fasteners and parts engineering solution including total 2D and 3D design. Instrumentele noastre de inginerie și proiectare includ o soluție completă de proiectare, inclusiv AutoCAD, și, Pro-E și Solidworks.

HZW expert team pay more attention to custom made stainless steel bolt quality support, domeniul de aprovizionare, inspecţie, standard de testare, ambalarea expedierii, service post-vânzare.

Here below is our custom stainless steel bolt quality checking items:

  • Toleranţă, main dimension, surface, mechanical property inspection
  • Torque coefficient, guaranteed load, hardness, wedge load, anti-slip coefficient, tensile load, rezistență la tracțiune, etc
  • Metallographic inspection and analysis (microstructure analysis, microhardness test)
  • Material chemical composition analysis, non-destructive testing, stress testing
  • Standard detection

5.Custom Made Stainless Steel Bolt Heat Treatment

custom made stainless steel bolt heat treatment

Some heat treatments such as annealing soften the stainless steel bolts, while others harden and strengthen them.

Tratamentele termice de recoacere sunt folosite pentru a elimina stresul rezidual, îndepărtați lucrul la rece și dizolvați elementele de aliere sau segregarea și asigurați un material mai omogen.

În timpul călirii și călirii, stainless steel bolts are first heated to a temperature where their structure transforms into austenite and then quenched or rapidly cooled in water, ulei sau aer la o temperatură la care structura cristalină se transformă în martensită.

We have some skilled experts who only handle heat treatments so the quality of work done on your bolts products is of exceptional quality.

6.Custom Made Stainless Steel Bolt Cleaning

custom made stainless steel bolt cleaning

There are two main cleaning processes in the bolt industry: one is cleaning before heat treatment, mainly cleaning the residual cooling oil, cooling liquid and anti-rust liquid and other attachments in the previous process.

The second is cleaning after heat treatment, mainly cleaning the residual quenching oil after quenching.

According to the cleaning method and principle, poate fi împărțit în: physical cleaning, chemical cleaning, etc.

1. Physical Cleaning: Physical cleaning refers to the use of various mechanical external forces and energy to smash, decompose and peel off the surface of the object, so as to achieve the cleaning effect. Commonly used methods are spraying, high-pressure water jet, agitation, ultrasonic cleaning, etc.

2. Chemical Cleaning: Chemical cleaning refers to the use of one or several chemical agents or other aqueous solutions to chemically transform, dissolve, and peel off the pollutants on the surface of the object with the help of cleaning agents to achieve the cleaning effect. Common cleaning methods include alkaline water cleaning, solvent cleaning, etc.

7.Custom Made Stainless Steel Bolt Surface Treatment

The metal surface finishing services commonly applied on various custom made bolts and nuts made of stainless steel materials, which can improve the appearance, adherence, solderability, resistance to corrosion, hardness, conductivity and many other characteristics of industrial components.

Surface finishing services including anodizing, pasivare, periaj, lustruire, înnegrită, placare, pictura, acoperire cu pulbere, tratament termic, fosfatarea la suprafață, galvanizare la cald, tratarea suprafeței dacromet, etc.

Clienții pot alege finisarea corespunzătoare a suprafeței în funcție de propria lor utilizare.

HZW offers a high quality surface finishing service for custom made bolts and nuts regardless of the machining method used in producing them.

8.Custom Made Stainless Steel Bolt Sample Inspection Before Mass Production

Custom made stainless steel bolt reliability and performance can only be ensured by sample inspection. So we make sure 100% sample testing before customer place the mass production order.

Since heat treatment can impact on its final properties, it is especially important to conduct testing on the stainless steel raw materials, after heat treatment and on the finished bolts products.

The diversity of stainless steel bolt types, sizes and end-use applications presents a challenge in testing that often requires choosing appropriate test methods, from simple dimensional checks to rigorous mechanical testing methods.

Common types of tests are followed: tolerance, outside dimensions, surface, fatigue, rezistență la tracțiune, wedge tensile (10 degrees), double shear, hardness, stress rupture, stress durability, pull-out/push-out, vibration, engagement, wear, microstructure, chemical analysis and corrosion.

9.Custom Made Stainless Steel Bolt Mass Production
