Calculate The Price Of Injection Mold
First, we should choose the steel and manufacture process base on customer requirements.
After choosing the material, we should make a plastic molding company simple draft, then we will get the mold size and weight.
Manufacture cost, the manufacturing cost is 1.5-3 times of material cost base on complexity.
Every mold should consider racist cost, it normally is 10% of mold price.
The tax depends on local policy.
The design fee, normally it is 10% of the total mold cost.
The trial fee is 3-5% china injection molding of total mold price.
The way of injection mould price calculation
Mold price=steel cost+design fee+manufacture cost+profit+tax+trial cost+package and transport fee
Material cost: steel and standard injection molding china spare part take 15%-30% mold price
Manufacture and profit: normally 30-50% of mold cost
Design fee:10-15% of mold cost
Trial fee: within 3% for big size mold,5% for a small mold
Package and transport: real cost or 3% mold price
VAT: 5%-17% of mold price
To ensure that the cost of the mold, cost control, quality. And delivery is proportional to the relationship between the quality of the mold to do a one-time. Few changes, delivery to shorten, so that low manufacturing costs, earn high profits. A market order to undertake the process of unique competitive advantage. On the contrary, enterprises not only no advantage but also will not make money or even lose money. Therefore, mold manufacturing costs, production management in the control part is very important, from the following aspects.
The effective management of product data management, process data management, drawings, document management. Effective product data management, process data management, drawing document management. It can ensure a comprehensive document. The consistency of the version of the drawings. Effective sharing, and effective query utilization.
Always consider part extents. In molding-speak, that means how big is the part. And will it fit comfortably in the mold while allowing for sprues, runners, ejector pins? And all the other considerations needed to make a mold work. Protolabs’ maximum part size for injection molding is currently 18.9 in. (480mm) by 29.6 in. (751mm) with a maximum depth from the parting line of 4 in. (101mm) deep. However, larger parts like these, in turn, require a larger mold. This may have an impact on your mold and part costs.
Optimize Part Design:
Wall thickness is one of the most important factors with part design. The first rule of thumb is to determine the minimum wall thickness that will meet your design requirements. It is always good practice to work with our injection molder/design engineer to check thickness specifications for the material(s) you are considering for your part. Typical wall thickness ranges from .04 – .150 for most resins.
Important wall-thickness facts:
Thinner walls require easier flowing plastics.
Longer flow lengths (distance from the nozzle to the furthest corner of the part) may require thicker walls.
Undercuts are a feature that can add to part complexity and cost, and in some cases can even prevent part ejection. This feature is created by including holes or snaps and should be eliminated when possible. One solution would be to work with your design engineer and injection molder to include a side action, sliding shutoff, or pick out.
Using sliding shutoffs, pass-through cores, or changing the parting line and draft angles may provide an easier mold build. These also reduce tooling and manufacturing costs.
Maintain the mold drawings, processing technology, and physical consistency. And the integrity of the data: through effective, detailed, rigorous testing means to ensure that the mold drawings, processing technology. And physical data consistency and integrity.
Optimized Mold Design:
How many times have you encountered an issue in production that was the result of inadequate mold design? If the issue persists or is unresolvable with various tactics. You may have to modify or re-create the mold – both of which are expensive solutions. To avoid these costly situations, it is essential to review mold design in the early stages.
Additionally, in-mold design, it is beneficial to be able to produce as many parts as possible in a single shot. The ability for the plastic to eject quickly without wasting time/movements is another critical cost-savings factor.
Integrating the issues and recommendations identified in the design and simulation phases is a key aspect of effective mold design review. However, a mold’s true performance also relies on part design.
Project planning, design, processing technology, workshop production, equipment, human resources. And other information organically organized, integrated together to coordinate the planning and production. To effectively ensure the quality of mold and pay as scheduled goods.
Mold production management processes
To develop a complete, practical mold production management system. Mold production management processes to achieve product data management. Process data management, project management, progress management of computer information management system. Including mold production planning, mold design, process Production scheduling. Real-time bar code submission of parts progress, product inspection, warehouse management. Mold manufacturing and related auxiliary information from planning. Manufacturing process control to the completion of delivery to achieve full-time real-time tracking management.
The establishment of processing technology:
The establishment of processing technology, a summary of mold parts list, purchased parts list, standard parts list, self-made standard parts list, bill of materials, heat treatment list, wearing parts list, and die costs. To ensure that relevant resources in place in time. Combined with production planning management, schedule management. To ensure that related equipment can be effectively used to prevent staff from idle. So that all aspects of processing and manufacturing can be interlocking.
The establishment of an all-round assessment system:
Accurate, original, true data to assess each employee correctly. Regular training related to mold design. Mold manufacturing personnel, find and train the backbone of the company’s elite team.
Regulate the functions of the post.
Establish a follow-up project management team:
Conduct detailed business and technical aspects of communication. Comprehensive and detailed understanding of the customer’s mold technical requirements, record. Summarize the content of the communication and accurate communication with the ministries. To avoid repeated, Modify, rework, thereby saving costs and time.
CNMOULDING for each customer to gradually establish a customer business and technical information repository, shared within the company. In order to improve customer service levels, reduce errors. Follow up, monitor the progress of the mold project production, arrange trial mode. The progress of the relevant materials with the reminder, model testing to confirm, send samples, arrange mold shipments, and other matters.
