关于消失模铸造的工艺特点有哪些？下面，为您详细讲讲：
What are the process characteristics of lost foam casting? Next, let me explain in detail:
一、模型是整体的，不用砂芯，省去芯盒、芯骨，不用配置型砂和芯砂；不用取模、修型、下芯、合箱。从而简化了工序，缩短了生产周期，提升了生产速率。由于用干砂，开箱变得容易；无飞边；易清理、打磨；粘模、粘浇道等劳动强度低。特别是白区的作业环境很干净。
1、
The model is integral, without sand core, core box, core bone, molding
sand and core sand; No need to take out molds, repair molds, lower
cores, or close boxes. Thus, the process is simplified, the production
cycle is shortened, and the production rate is increased. Due to the use
of dry sand, unpacking becomes easier; No flash; Easy to clean and
polish; The labor intensity is low for sticking molds and pouring
channels. Especially the working environment in the white area is very
clean.
二、对铸件材质的适用性，一般来说，常用的金属材料都可用消失模铸造来浇注。
2、 For the
applicability of casting materials, generally speaking, commonly used
metal materials can be poured using lost foam casting.
三、对铸件大小的适用性，消失模铸造以500kg以下，壁厚大于4mm的铸件为宜。
3、
For the applicability of casting size, it is recommended to use
castings with a wall thickness greater than 4mm and less than 500kg in
lost foam casting.
四、对铸件生产批量的适用性，较佳的生产批量考虑模具的成本，要求有大的批量(年产万件以上)愈合算。
4、
For the applicability of casting production batches, the optimal
production batch considers the cost of molds, and requires a large batch
size (annual production of over 10000 pieces) to be more
cost-effective.
五、消失模铸造不存在与分型和起模有关的铸件结构工艺性问题，特别适合于具有复杂内腔结构、模样分型困难、造型困难的铸件。
5、
Lost foam casting does not have any structural and technological issues
related to parting and stripping, and is particularly suitable for
castings with complex internal cavity structures, difficult pattern
parting, and difficult modeling.
六、铸件质量，尺寸精度泥杆 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修 托辊生产线提升(达CT6~CTg级)，件重可减少10%~20%，可提升工程机械的整机性能。
6、
The casting quality and dimensional accuracy have been improved (up to
CT6~CTg level), and the piece weight can be reduced by 10%~20%, which
can improve the overall performance of construction machinery.
七、因加工性能，减少加工余量(15%~30%)，可减少刀具消耗，节约加工工时，实现节能减排。
7、
Due to processing performance, reducing machining allowance (15%~30%)
can reduce tool consumption, save machining hours, and achieve energy
conservation and emission reduction.
八、对于结构复杂的大中型箱体铸件可以实现集约化、规模化生产，具有工艺竞争力。
8、
For large and medium-sized box castings with complex structures,
intensive and large-scale production can be achieved, and they have
process competitiveness.
