Key Elements to Consider Before Proceeding with Die Casting

Getting your product from the drawing to a tangible version is a crucial aspect of design. Without it, you have no way to test and validate your design before it's finalized for mass production. Die casting is one of the ways you can bring your designs to life. It involves die casting – molds manufacturing – CNC machining, which delivers high precision, fast, and durable prototypes of parts from a billet or block of your chosen material that is cut with a series of drill bits and tools.

Are you considering die casting for your project? Be sure to consider these Key Elements to Consider Before Proceeding before you proceed:

Die Casting Materials

Die casting allows you to volume make your model with almost all kinds of materials that can withstand heat and stress. Some of the most popular materials used are aluminum, zinc, and special alloy like magneium and copper.

Die Casting Machining methods

Die casting uses the cavity of the mold to apply high pressure to the molten metal. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding.

Your Die Casting project

Die casting is used typically for volume building high-quality prototypes for functional testing. However, it's also practical for crafting custom casts or molds to build prototypes for other production processes, such as injection molding. In this case, the CNC machining prototyping process also qualifies as rapid tooling.

Die Casting Tolerances

CNC machines can be very accurate, but running the mill on the highest accuracy can be time-intensive and costly. That's why tolerances are used, and these are measurements indicating the level of precision required for the prototype you're making. In short, they represent the degree of variation permitted in the measured value or final dimensions of the part. Reputable providers of CNC prototyping and edm wire cutting services control their tolerances to DIN-2678-1 Medium for Fine for metals.

PTJ RFQ

What Is PTJ?
PTJ adopts flexible manufacturing methods to help our customers to control the product cost but best quality guranteed. Some frequently used machining processes include CNC milling, CNC turning, precision grinding, EDM machining, laser cutting, welding, CNC punching, sheet metal stamping, profile extrusion, die casting, forging, and more. Most of the custom precision cnc machining china parts and plastic machining components we made are related to automation machines, robotics, medical devices, fiber optics, aerospace/aircraft, test and measurement, sensors, telecom components, scientific devices, audio equipments, bicycles, boats, camera, cars, drones, electronic enclosures, front panels, furniture and architecture hardware, lighting, motorcycles, scooters, utv, jeeps, trucks, sports equipments, machinery, music instruments, and so on.
For Surface Finishes
Thanks to our mature supplier management and continuously experience accumulation. Now we have very stable surface finish suppliers to assist us to do different surface finishes with stable and excellent quality. Some Frequently used surface finishes are Anodizing, Oxide, Nickel Plating, Chrome Plating, Gold / Silver Plating, Powder Coating, Zinc Plating, PVD Coating, Passivation, Heat Treatment, Electrochemical machining, Brushing, Polishing, Sandblasting, etc.
General Tolerance of Equipments
1. CNC Milling tolerance: +/-0.01mm
2. CNC turning tolerance: +/-0.01mm
3. Precision grinding tolerance: +/-0.005mm
4. EDM machining tolerance: +/-0.005mm
How to Control Quality?
1. Inspection by machinist himself who is responsible for a specific part machining.
2. First article part inspection by QA.
3. IPQC patrol inspection during production.
4. PQC inspection before shipping according to ISO9001 sampling inspection standard for large quantity production. And for small quantity, 100% full inspection.
5. Material Certificates and outgoing inspection reports could be provided.
Our CNC machine and swiss machining shop sets full and advanced inspection instruments such as CMM, projector, height instrument, industrial microscope, micrometer, calipers, thread gauges, pin gauges, block gauges, etc. so as to inspect all details on drawings and confirm quality is good and issue the ourgoing reports accordingly.
How to Start Working with Our Company?
1) Sending detailed RFQ with 2D and 3D drawings to through email to info@pintejin.com. General drawing formats like PDF/ STEP/IGES/X_T etc are accepted.
2) We check and confirm about materials, surface finish and quantiy, and evaluate. If any question, our sales engineer would double check with customers until everything is clear. We will quote accordingly if we are ok to make the parts with best quality. If no question and everything is clear, we send quotation with best prices within 24 hours. Our sales engineer team is online for 7/24 for offering customers the best cnc machining services.
3) We recommend to start from few pcs prototypes for approval at the beginning. If nothing wrong after customer’s test and approval, then we proceed to volume cnc manufacturing.
Some Tips for Customers
a. We accept Paypal payment of small amount payment for samples or small batch orders for building mutual trust at the beginning. General payment terms is 30% by wire transfer, and balance before shipping.
b. Delivery time for few pcs samples are generally 5 to 7 days, and 15 to 25 days for volume production. If the order quantity was too big, we would check and confirm delivery time sepertely.
c. Our company has concrete promise to all customers that if any quality problem caused by our factory, we would remake all parts for free or send money back.
Safe Packing Methods to Prevent Goods from Damage during Transportation
Due to long distance transportation to overseas countries, safe and strong packing is very important to gurantee the parts to be in good conditions when arriving at customer’s hand. We choose different packing materials according to different parts and quantity. Some commonly used packing materials are pp/bubble bag, oil paper, foam, blister tray, 5 layer carton, wood box, etc. See below some packing pictures.
