How to do injection mould design?
A good mold design is the critical start. With your part drawings (2d/3d), our designers and engineers will have a meeting to discuss the part structure, difficulties, customer's requests and have a concept of mould design for it. 1. DFM: show the mould layout concept, cooling, injection system, ejection system, wall thickness, draft angle, engraving, surface finishing, design failure mode and effects analysis and other mould release issues. 2. Mold flow (offer within 1~3 days) 3. Mould 2D layout design (offer within 2~4 days) 4. Mould 3D design (software: UG, offer within 2~5days) What is a good mold? It must have good quality to meet production requests stable and smoothly, and no need to spend too much time & cost for maintenance and repair. Suntime has 6 designers in total with more than 5-10 years’ experience, they always pay special attentions on customers' specification and details by thinking about the cost-saving solution based on stable and good quality. Their years’ experience for exporting molds give them great knowledge for global mold standards and quality demands.Injection Moulds Gallery
Please send us part 2D/3D drawings for a quick quotation. If no drawings, clear photos showing the structure and dimension, or, samples to our factory directly. File format: Dwg, Dxf, Edrw, Step, Igs, X_THow to do project management for injection mould manufacturing?
What we do for your project management (work flow)? Step 1: With customers' parts drawing (2D&3D) and specification, we hold kick off meetings with designers, engineers and operation manager together to learn details and make memo for the projects. Step 2: After customers approval for DFM, they start the 2D layout & 3D mold drawing & Mold flow analysis in short time. Step 3: During all the process, weekly report will be provided every Monday to make sure customers have all things under control. Step 4: For mold trials, we send trial report with mold photos, samples photos, short shot photo, weight photo, moulding issues and our solutions. Meanwhile, Moulding video, inspection report and moulding parameter will be provided as fast as possible after. Step 5: With customers’ approval to send samples, we send parts by express under Suntime's account. Step 6: Mold corrections or modifications will be started at once after communication with customers. Step 7: Mold can be shipped with customers' approval. More than 50% molds were required to ship after T1. Step 8: Shipping package including: memory stick with final 2D&3D mould design, BOM, material certifications, photos and some spare parts. Step 9: Clean molds and double check with QC checking list before packing. Step 10: Vacuum packing for transportation. Step 11: Documents and sales support for custom clearance.

Injection mold manufacturing process and cost
The process of making a plastic injection mold can be broken down into the following steps: Design: DFM analysis for mouldability. Create a 2D&3D mold drawings. Machining: Cut steel and use machines like CNC, EDM, lathe and others to make the shape based on drawings. Hardening: Heat treat the metal to make them reach to the hardness and more durable. Surface: Polishing and textures to meet the cosmetic requests. Assembly & Fitting: Put together all components of the final mold and do fitting. Mold Testing: Test that everything is functioning properly after assembly. Inspection: With molded parts, make inspection of molds and samples by CMM, projector, etc,. Corrections/ modification: According to the samples, make corrections or modifications that customers required. Ship molds after customers' approval.
How to save cost for mold making? Firstly, you should know the purpose of the mold. What are you going to use it for? What are the dimensions of the object you want to create? What is the annual volume? How many cavities do you need? And how accuracy you want? All of these factors will affect the cost of the mold. • Simplify the design as much as possible. The more complex the part design is, the more expensive the mold will be. If you can simplify the design, you will save money. • Use standard materials. The cost of an injection mold can be reduced by using standard materials instead of exotic materials. • Use a simple geometry. The simpler the geometry, the less expensive the mold will be. • Minimize the number of parting lines. Parting lines are where two halves of the mold meet. The more parting lines there are, the more expensive the mold will be. • Minimize the number of cores and inserts. Cores and inserts are pieces that are used to create cavities in the mold. The more cores and inserts there are, the more expensive the mold will be. • Use a conventional manufacturing process. The cost of an injection mold can be reduced by using a conventional manufacturing process instead of a custom process. • Use a simple gate design. The gate is where material enters the cavity of the mold during injection molded manufacturing . A simple gate design will reduce both material waste and cycle time, which will save money.
